The fuzzy ball display is actually quite usefull for sound engineers because it lets them, combined with a multiband EQ, see exactly where in the stereopanorama a certain frequency band is. So when mixing a song you usually want the bass in the center and the high frequency stretched out into the panorama to have a good room/stereo imagery.
Oh My GOD! The memories!!! I had an oscilloscope hooked up to my stereo when I was in high school (around 1967 or so). Was so much fun to watch the wave forms run across the screen. I set it up so the left channel was the horizontal and the right channel was the vertical. So much fun....
This is a beautiful system. Makes audio look really cool with those level meters and oscilloscope. I could never get one though because I would probably go insane trying to make all my old HiFi equipment to play perfectly, something that I am terribly ill-equipped to do. All I can fix is mechanical stuff, electrical repairs are above my pay grade. But not for lack of trying! Great video Techmoan, thanks for all the great stuff you do and show us.
Very fancy indeed for the early 70’s. I would have absolutely loved this unit back then. Thanks Techmoan. Keep up the good work, we’ll keep digging it...man!
twocvbloke I see where you're going, but i'd like to point out that LGR is more into retro computers; some of the more likely connoisseurs of this particular piece of kit would be e.g. databits, VWestlife, or Technology Connections.
Omg Techmoan, why do you keep doing this to me! You find some awesome, obscured Hi-Fi thing that costs an arm and a leg, then you also have the Techmoan affect, where it then gets double the price, and I want one and can't find it or afford it! :)
Maybe we can manufacture new ones? Of course no CRT, but TFT. Would people buy one as a DIY kit that requires sourcing a $100 enclosure from China separately?
This is why when you have multiple of weird hifi devices to sell, you give him one for free or a discount, and then wait for the price to rise on the remaining ones.
I only see this machines whenever I go to a friends house where their parents are working in UK, US or Japan. They're fun to look at and also to listen to those warm well balanced base and treble sounds.
If you have a look at the manual, it shows this is meant to be fed from your receivers Amp via the speaker output, split with a Y cable of some sort to the speakers. I would guess you could run this off of an unused Speaker output ( Speaker B if you are only running Speaker A for example ) the Multipath option is meant to go to a tuner which specifically has that option, and it is meant for FM only. Manual is free on hifiengine.
i love all those vintage 70's and 80's stereo equipment. If i only knew better, then i would have starting buying them all up in the late 80's early 90's, because in those days, people practicaly gave al these fine equipment away in garages sales and flee markets
Absolutely love your videos! Wish I'd have found them sooner! Superb, quality content and love the retro audio equipment reviews, as it brings back quite a few memories.. plus, some of the stuff you review I had never heard of way back then! Looking forward to your next video.
A very cool accessory. There where several Pioneer and Marantz quadraphonic receivers that had the scope built in to the receiver, and most quad receivers did have 4 VU meters built in so you could set levels and balance things with a test record.
My Pioneer system lives in a networking-cabinet with the direct-drive record-player sitting on top! The steel cabinet itself is extremely sturdy & will outlast anything made from particle-board or mdf, plus it has the the advantage that components can be either rack-mounted or sat on rack-mounted shelving as I've done (easier than trying to find brackets the right size & longer case screws)!
There are likely VU calibration adjustments in the unit. If you can find a service manual it should show how to re-calibrate the meters. Your videos bring back memories, I was an electronic repair tech in the early 1970's...worked on lots of consumer electronics.
Wow, you put that into your system with the CRT scale installed backwards. That would keep me up at night, so I would definitely have taken it apart as far as I had to, to flip that thing around!
I bought one of the SD-1000's years ago for $25 through Craig's list. They are now worth over $1000 and very rare. My scope tube is still good and I have upgraded some of the electronics in it. I also was able to get a service manual from Pioneer for it with schematics. I would NEVER part with it as I really like it and it is useful, although you can only look at 2 channels at a time, but can select any combination of 4 inputs with the push buttons. The SD-1100 is capable of displaying all 4 channels in quadrature on the scope, so I modified my 1000 to do that too! Realize that you have a VERY rare piece of equipment!
on the board that the needles are attached, you'll see a flathead much like the on the front under display. they may tune the level like you want. on the needles. awesome gadget by the way! I'm jealous!
The use of binding posts and that 20 dB attenuation made me wonder if those rear panel inputs were intended to be used for speaker-level signals, so you could compare the output of your amp to a line level signal from the same source. But I don't know enough about electronics to know if that'd even be a useful thing to do.
bingo!. you would want to scope the amp as It may be the weak part in the old system. clippping any one ?:) You could do a slick Bode plot with this ..
That's the reason that thing has a sweep generator on the oscillator. There's probably a feature on it that actually *does* a Bode plot if the phosphor on the tube is slow enough.
the EE in me is happy.......... Irony my first scope when I was 13 was a modded 5 inch BW TV added a BNC jack to the vert coil and volla fixed sweep rate audio scope. fun times
I was writing an oscilloscope program for audio that did sweep only and immediately added XY mode after seeing this. Even got it to rotate the points 45 degrees so left and right would be flat. Thanks for the inspiration!
My Marantz 19 Receiver has a small scope and it's fun to watch the stereo signal. You can tell if a station is broadcasting in stereo but the source is really mono. It also shows multipath for turning your antenna toward the station.
Having cooked a lot of Pioneer equipment of that vintage, a nice addition to any of it is a PC cooling fan to get some airflow through the cab. Passive doesn't cut it forever.
There was also a scope mfgr'd by Kenwood the KT-6000 (circa 1970). I own it. I recapped it and it still works fine. It's got FM-multipath input also. The cost was around $200.00 in 1970 dollars.
I have a Hifi set up in my room. I have a Sony TA-F40 amplifier, a PYE Cambridge 9123 Reel to reel, a Denon DRM-550 cassette deck, an 8 track player and a Dual 505 Mk2 turntable. The amplifier is wired up to two sets of speakers and it sounds very nice. The stylus I use for the turntable is a Nagaoka MP-100 and the cartridge is a Nagaoka MP-11. There are small VU meters on my amplifier and I have to turn it up a quarter of the way to get the sound to register on it.
I frankly like the looks of this older version a LOT more than the updated version. And I'm quite impressed that RUclips's sound compression didn't clip and distort the crap out of that sine sweep
Cool gear indeed. I acquired (from an elderly friend) the Heathkit AD-1013 unit shown in the old advertisement. My friend had built the kit himself and had kept the original manual, but It's been a long time since I saw it in his stereo rack. I cleaned it up and performed the calibration procedure a few times. The generator is quite good but the scope is small and has no useful scale markings. So I've decided it's basically a toy and to keep it in my static "museum" shelf, without taking the time to do a full refurbishing (replacing caps and other off spec components). Thanks for the video.
This has become my absolute FAVORITE channel on RUclips. In fact, when I go to my local record store (and they indeed sell vintage audiophile equipment such as reel-to-reel machines, speakers, etc.), I rant and rave about this channel. I hope I boosted your sub count by some small way! Take care, and keep doing what you do!
There were Hi-Fi cabinets going back to the 50's. Even in the 60's they were putting out such consoles that had a phonograph, radio and even a TV set built-in.
I know the history. A rack of HiFi components in the corner of the room was not a *common* thing in houses until the late 70s...through to the 80s. Yes people had radiograms, stereograms, record players with built in radios before, but a rack of HiFi gear?....A few enthusiasts. Try finding a HiFi shop in the average British town in 1965. However go into the average house in the UK in 1987 and you’d find a midi stack system with smoked glass doors, containing a record player, radio, cassette, perhaps a CD player, graphic equaliser. The majority of people today don’t have a separate HiFi in their house. No one I personally know other than myself does...but in the 1980s everyone I knew had one. My parents didn’t and my grandparents didn’t.
these have gotten VERY expensive in recent years, the SD-1000 will run you around $1000, and the even more sought after SD-1100 I have seen sell for nearly $2000. There are far cheaper and probably far more reliable oscilloscopes you can get for far cheaper, just this one is vintagy and awesome and everyone wants one.
that's just it, these things are really cool, and vintage, but unless you can get them cheap, and that's never gonna happen, I'd personally rather just have something newer, cheaper, and more reliable.
they do but it's boxier and not as interesting to look at or have in your "Vintage looking" hi-fi. Hewlett Packard (the computer and printer company) made a ton of different models of these machines throughout the 80s and 90s, but they look kinda ugly and don't go well with most hi-fi components due to their odd sizes.
true but if you wanted to buy one of these lets say 15 years ago, you would have spent maybe $200 at most for one of these units as they just weren't that popular for most people at the time.
have to say, this is giving me a righteous nerd-on. i love attaching crts to my audio signals. from electronic grade oscilloscopes, to strapping audio signals via a transformer to the coils of a of a tv tube , driving sound thru a crt always gives interesting results.if you have a squggly tube.. or an old crt tv, you can do this. fiddle with the signals, its most esmerising
Man, I wish I could get my own wayback machine. I'd have all the things! Also, my Dad had a 4 Channel setup when I was kid. It was like magic to me. Then the Sansui receiver took a dump :(
Speaking or room mmeasurments, another piece of gear popular with Hi=Fi enthusiasts were room analyzers. They combined a graphic equalizer with an LED or vacuum flourescent spectrum display with the same frequency bands. I showed up too early at a rock concert in the 80's and had a good view of the sound engineer and his equipment. He was running frequency sweep and white noise tests that were so loud I had to plug my ears with my fingers. The band sounded great so it must have worked.
wow lovely bit of kit. I use to have a small oscilloscope connected to the RCA low output of my HiFi as a Teen. well i say small, the screen was but the thing its self was the size of a small house. but it was free. :)
Epic video, so pleased you got one and did this video about it, thought I was in Hardman Radio Manchester again ( they were bought out by Laskys by your day) brushed aluminium and wood oh happy days
The volume is not the issue for me, it's the frequency. Even at very low volumes, extremely high frequencies hurt my ears and feel really uncomfortable, to the point I've actually gotten really nauseous from something like a car breaking or a TV tube being turned on.
Very cool! I imagine that, with enough practice, you could gain an intuitive reading of the "ball of steel wool" and be able to diagnose quite a lot from that quasi-3D display.
FM radio reception suffers from a flaw called "multipath". The signal transmitted from the antenna goes out in all directions and the signal is reflected by buildings, mountains, etc. These signals arrive at the radio's antenna in and out of phase, slightly delayed with respect to each other. The best way to combat this is to physically turn the antenna for the strongest signal. With the multpath jacks (which have to be outputted on the receiver) you would hook them up to the SD-1000 and then turn the antenna looking for the least distortion/amplitude signal on the scope. On my Pioneer TX-9500 II it has a multipath switch on the front panel and when turned on as you turn the antenna you look for a dip in signal strength.
The rear ports are intended to have the output from your amplifier that would go to your speakers so that you can analyze all four channels of the system as they would be sent to the speakers. The line level inputs are placed in the front to check audio sources, like a phonograph (hence why is is so sensitive to normal line in levels), tape deck, or radio receiver. I don't think the designers intended for this to be hooked up and on all the time since it does not have pass through connections.
Man, I *really* miss the VU Meters and Spectrum Analyzers.. I've kinda been on a recent quest to find and incorporate these back into my 'modern' amps and AVRs. Not as easy as it seems though.
Cool video. It was quite interesting to see that the audio output of the laptop was so much worse than the signal from you High-res audio player. It goes to show that 'digital' sound isn't all of the same quality using different devices.
To me, a goniometer is a device for precisely controlling the angle of something, usually some kind of instrument. Maybe this usage comes via metonymy from the galvanometer actuators used in a laser projector, which could, I guess, be called goniometers.
When I get out the army (and the damn barracks) I'm going to have a dedicated HiFi set up I've been wanting one since I was stationed in Korea, and yours looks absolutely amazing
Looks like the right-hand meter has either a magnetization issue or it has just jammed mechanically. For the enthousiasts who are into adjusting their system to perfection, especially when it comes to tape and phono drives, you can get an entry-level LCD storage oscilloscope for a few hundred quid. They often have real-time analyzers as well so they're a very useful tool to have if you do something that involves electronics.
It's the sort of device that would be relatively easy to replicate using modern tech, but next to impossible to properly duplicate. Sure, a computer could put lines on a screen, it might even put them in the same places, but this device uses the signal to paint the image directly, and that's kind of special.
The plastic sheet with the numbers and scale written on it is called the graticule and the fact that it is in backwards likely means someone had the tube out at some time, hopefully you have a nice new one. Looks like there's lots of finger marks around the knobs so it might have been worn out. I used to repair and calibrate instruments for engineers and scientists so seeing it in backwards makes me cringe, also I would have been scolded for encouraging inaccurate readings as the emulsion side of the marking should be touching the front of the scope to reduce parallax. ;)
Matt, thank you so much, from Western Canada, for your well thought out and edited sharing and for hunting this sh!t down to make us drool. Bravo! love the retro videos.
Congratulations on your new acquisition..from the 8 bit guy's behalf... ...I follow you both for the amazing content you make...you could let fans congratulate you on each others behalfs.
Thanks for another excellent review! I have often wondered what could be done with one of these devices and have thought about adding one to my vintage setup.
The fuzzy ball display is actually quite usefull for sound engineers because it lets them, combined with a multiband EQ, see exactly where in the stereopanorama a certain frequency band is. So when mixing a song you usually want the bass in the center and the high frequency stretched out into the panorama to have a good room/stereo imagery.

This device makes audio visually pleasing. Superb video.
DR DCC but does it make video audibly pleasing?
Wonderful! What I like the most about the oscilloscope is the movement of the beam as the capacitors discharge after the machine is turned off. (2:25)
Very fancy indeed for the early 70’s. I would have absolutely loved this unit back then. Thanks Techmoan. Keep up the good work, we’ll keep digging it...man!
Well, it's woodgrained, should keep an LGR happy at the very least... :P
twocvbloke
I see where you're going, but i'd like to point out that LGR is more into retro computers; some of the more likely connoisseurs of this particular piece of kit would be e.g. databits, VWestlife, or Technology Connections.
LGR is a hifi enthusiast as well, he's got a complete hifi setup that makes random cameos in his twitter posts
Amir Pourghoureiyan
Oh i didn't know that - i don't use twitter myself you see - but i thank you for the heads-up! :)
another vacuum cleaner fan in Techmoan's audience!! Such fun.
twocvbloke my dog didn't even notice it.
Omg Techmoan, why do you keep doing this to me! You find some awesome, obscured Hi-Fi thing that costs an arm and a leg, then you also have the Techmoan affect, where it then gets double the price, and I want one and can't find it or afford it! :)
Michael Cawley it's exactly what I thought sir. And damnit, I want one too!
Maybe we can manufacture new ones? Of course no CRT, but TFT. Would people buy one as a DIY kit that requires sourcing a $100 enclosure from China separately?
This is why when you have multiple of weird hifi devices to sell, you give him one for free or a discount, and then wait for the price to rise on the remaining ones.
"The Techmoan Effect" i love that phrase! :D haha
id try and rig up an oscilloscope to the speaker output.
I only see this machines whenever I go to a friends house where their parents are working in UK, US or Japan. They're fun to look at and also to listen to those warm well balanced base and treble sounds.
I always enjoy seeing retro devices appearing on your channel, my favourite type of content.

I remember when these came out. I lusted over one, but it was out of my range at that time.
Damn you are old, bruv.
Thanks for sharing this esoteric info!!! I love it. And the silver-front design of that era was SOO COOOL
Absolutely love your videos! Wish I'd have found them sooner! Superb, quality content and love the retro audio equipment reviews, as it brings back quite a few memories.. plus, some of the stuff you review I had never heard of way back then! Looking forward to your next video.

Techmoan, you are the Pioneer of vintage tech videos on RUclips.
reeffeeder I see what you did there
And not too technika.
Mike McL well played
Absolutely love your videos and your passion for vintage gear, thank you for bringing this gem to life!
For anybody wondering, song played from vinyl for a few seconds: Rob Base & DJ EZ Rock - It takes two
There are likely VU calibration adjustments in the unit. If you can find a service manual it should show how to re-calibrate the meters. Your videos bring back memories, I was an electronic repair tech in the early 1970's...worked on lots of consumer electronics.
Oh man. I've lusted after this thing for decades. Super envious.
Wow, you put that into your system with the CRT scale installed backwards. That would keep me up at night, so I would definitely have taken it apart as far as I had to, to flip that thing around!
Love the new HiFi cabinet, would also love a tour of everything you've got in it!
Those knobs are used in Marshall guitar amps. You can buy them in Europe in stores like musikding, banzai music, etc.
Yeah i though i recognised them from my Marshalls.
I bought one of the SD-1000's years ago for $25 through Craig's list. They are now worth over $1000 and very rare. My scope tube is still good and I have upgraded some of the electronics in it. I also was able to get a service manual from Pioneer for it with schematics.
I would NEVER part with it as I really like it and it is useful, although you can only look at 2 channels at a time, but can select any combination of 4 inputs with the push buttons.
The SD-1100 is capable of displaying all 4 channels in quadrature on the scope, so I modified my 1000 to do that too!
Realize that you have a VERY rare piece of equipment!
My grand father had one of these until mid 90s or so never found out what happened to it. Had to be my favorite device of his.
on the board that the needles are attached, you'll see a flathead much like the on the front under display. they may tune the level like you want. on the needles. awesome gadget by the way! I'm jealous!
The use of binding posts and that 20 dB attenuation made me wonder if those rear panel inputs were intended to be used for speaker-level signals, so you could compare the output of your amp to a line level signal from the same source. But I don't know enough about electronics to know if that'd even be a useful thing to do.
bingo!. you would want to scope the amp as It may be the weak part in the old system. clippping any one ?:)
You could do a slick Bode plot with this ..
That's the reason that thing has a sweep generator on the oscillator. There's probably a feature on it that actually *does* a Bode plot if the phosphor on the tube is slow enough.
the EE in me is happy.......... Irony my first scope when I was 13 was a modded 5 inch BW TV added a BNC jack to the vert coil and volla fixed sweep rate audio scope.
fun times
Stoney3K I try Bode plots on analog scopes from time to time and the plot moves around the screen
I was writing an oscilloscope program for audio that did sweep only and immediately added XY mode after seeing this. Even got it to rotate the points 45 degrees so left and right would be flat. Thanks for the inspiration!

This is the coolest tech you have done, I have wanted one of these stereo displays for a long ass time. Im so jealous right now!
Beautiful piece of hardware.

Audio eye candy at its best. Love it!

Techmoan Yeah, I guess I'm thinking from an American standpoint here.
This is one of the coolest HIFI accessories I've ever seen
I have the Pioneer SX-626 , the one normal people would most likely buy, it´s still running strong and i used as the main stereo for the house.
Wow, what a sweet bit of un-essential kit. Damn, I want one!
these have gotten VERY expensive in recent years, the SD-1000 will run you around $1000, and the even more sought after SD-1100 I have seen sell for nearly $2000.

that's just it, these things are really cool, and vintage, but unless you can get them cheap, and that's never gonna happen, I'd personally rather just have something newer, cheaper, and more reliable.
Lassi Kinnunen Still not affordable, and worth the money that most people can justify spending.
If you just want a scope, grab a modern Rigol for half that money. But that's a purpose-built lab scope and not a HiFi component.
they do but it's boxier and not as interesting to look at or have in your "Vintage looking" hi-fi. Hewlett Packard (the computer and printer company) made a ton of different models of these machines throughout the 80s and 90s, but they look kinda ugly and don't go well with most hi-fi components due to their odd sizes.

What a lovely piece of kit. I think you're going to need a bigger house soon!
"Lots of stuff in there, that does... THINGS" Spare me your technical jargon, Techmoan! :)
Oh, but that is the stuff classics are made of!
For the Record stop your arrogance bro
Right! I so laughed when I saw your comment 😀
@@okktok I think the humour went right over your head "bro".
have to say, this is giving me a righteous nerd-on. i love attaching crts to my audio signals. from electronic grade
oscilloscopes, to strapping audio signals via a transformer to the coils of a of a tv tube , driving sound thru a crt always gives interesting results.if you have a squggly tube.. or an old crt tv, you can do this. fiddle with the signals, its most esmerising

This is the stuff i like. I watch techmoan for mostly audio equipment
What a COOL piece of gear! I wasn't aware it existed until...now!
Thanks to you, I now have both mailcall devices. My friends love playing with them.
Speaking or room mmeasurments, another piece of gear popular with Hi=Fi enthusiasts were room analyzers.

Oh boy my body just shivered with that sine wave test
Now this is something I could just sit and watch all afternoon!

That analog oscillator is the most coolest thing I've heard!
Nice you cover this. Almost bought one a year ago....
Wow i love vintage tech on this channel!
1:49 don't forget; the signal output of your laptop is a class D output, your sinwave is not real, but synthesized by PWM, wich increase the noise in.
I've got an old Technics hifi with EQ and all the goodies from the '80s and giant speakers - all sounds amazing and I got it off EBay for £90
You have a nice set up techmoan, that scope really sets the mood.Cheers
Appreciate that headphone warning, I have sensitive hearing as it is and high pitched noises like that really hurt my ears.
I always use volume normalization with headphones so I don't get nasty surprises.
The volume is not the issue for me, it's the frequency. Even at very low volumes, extremely high frequencies hurt my ears and feel really uncomfortable, to the point I've actually gotten really nauseous from something like a car breaking or a TV tube being turned on.
Doesn't matter while I'm still 29 does it? XD
Ethan Hall Stop being an ass. Your comments contribute nothing to the conversation other than showing how “mature” you are.
ganymedeIV4 Ha ha, well im almost 47 and i heard it all just fine and it was quite ear piercing.
I think the SD-1000 with the dark VU meters is actually cooler looking than the SD-1100. It has that futuristic dark styling that gets me somehow.
Those retro grooves are surprisingly modern.
Hands down, one of the best things I've seen and I actually want one. Great video
Very cool! I imagine that, with enough practice, you could gain an intuitive reading of the "ball of steel wool" and be able to diagnose quite a lot from that quasi-3D display.
Really cool. I was going to mention the backwards scale. The oscillator gave me a bit of a test of my laptop speakers. They're Altec Lansing.
I usually only understand about 1/2 or what he's saying..... and yet, these are the most fascinating videos on the internet........
FM radio reception suffers from a flaw called "multipath". The signal transmitted from the antenna goes out in all directions and the signal is reflected by buildings, mountains, etc. These signals arrive at the radio's antenna in and out of phase, slightly delayed with respect to each other. The best way to combat this is to physically turn the antenna for the strongest signal. With the multpath jacks (which have to be outputted on the receiver) you would hook them up to the SD-1000 and then turn the antenna looking for the least distortion/amplitude signal on the scope. On my Pioneer TX-9500 II it has a multipath switch on the front panel and when turned on as you turn the antenna you look for a dip in signal strength.
You should set the position of the scope trace on the centre with the vert position knob. Now it looks as if it has a DC offset.
That oscilloscope is very addictive to watch, looks a similar idea to that SAE tuner you reviewed a while ago.
Nice to see something my age look so youthful.
I used the ending credits to test out my new set of AKG Cans/Headphones! Thanks Techmoan... I really like the unit you showcased
The rear ports are intended to have the output from your amplifier that would go to your speakers so that you can analyze all four channels of the system as they would be sent to the speakers. The line level inputs are placed in the front to check audio sources, like a phonograph (hence why is is so sensitive to normal line in levels), tape deck, or radio receiver. I don't think the designers intended for this to be hooked up and on all the time since it does not have pass through connections.
Interesting bit of kit. I’ve never seen one before. Fingers crossed that you get the better version
Back in the 80s I used to build displays like that out of old TVS.
Man, I *really* miss the VU Meters and Spectrum Analyzers.. I've kinda been on a recent quest to find and incorporate these back into my 'modern' amps and AVRs. Not as easy as it seems though.
Cool video. It was quite interesting to see that the audio output of the laptop was so much worse than the signal from you High-res audio player. It goes to show that 'digital' sound isn't all of the same quality using different devices.
Beautiful vintage device this
The stereo phase display which you refer to as a "Lissajous display" is also known as a "goniometer" in some circles.
To me, a goniometer is a device for precisely controlling the angle of something, usually some kind of instrument. Maybe this usage comes via metonymy from the galvanometer actuators used in a laser projector, which could, I guess, be called goniometers.
I know dudes being hard-core audiophiles, who would KILL for a unit like this! You sure are lucky, TM!
When I get out the army (and the damn barracks) I'm going to have a dedicated HiFi set up I've been wanting one since I was stationed in Korea, and yours looks absolutely amazing
Good luck. Start small and take your time - shopping around for components is a big part of the fun.
Looks like the right-hand meter has either a magnetization issue or it has just jammed mechanically.
For the enthousiasts who are into adjusting their system to perfection, especially when it comes to tape and phono drives, you can get an entry-level LCD storage oscilloscope for a few hundred quid. They often have real-time analyzers as well so they're a very useful tool to have if you do something that involves electronics.
It's the sort of device that would be relatively easy to replicate using modern tech, but next to impossible to properly duplicate. Sure, a computer could put lines on a screen, it might even put them in the same places, but this device uses the signal to paint the image directly, and that's kind of special.
The plastic sheet with the numbers and scale written on it is called the graticule and the fact that it is in backwards likely means someone had the tube out at some time, hopefully you have a nice new one. Looks like there's lots of finger marks around the knobs so it might have been worn out. I used to repair and calibrate instruments for engineers and scientists so seeing it in backwards makes me cringe, also I would have been scolded for encouraging inaccurate readings as the emulsion side of the marking should be touching the front of the scope to reduce parallax. ;)
Love the new shelves. Great video.
Matt, thank you so much, from Western Canada, for your well thought out and edited sharing and for hunting this sh!t down to make us drool. Bravo! love the retro videos.
Congratulations on your new acquisition..from the 8 bit guy's behalf...
...I follow you both for the amazing content you make...you could let fans congratulate you on each others behalfs.
Nothing can beat an additional knob.
Well this cheered up an otherwise dull day. Thank you for sharing your passion, I always enjoy your work.
Brilliant! An expensive audio device sold to justify the purchasing of other expensive audio devices!
Love the way those needles dance to the music
Thanks for another excellent review! I have often wondered what could be done with one of these devices and have thought about adding one to my vintage setup.
The meters aren't labeled Left and Right, like the Sony, they're labeled Vert and Horiz. Might be the difference.
