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!
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.
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.
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 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!
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!
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
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.
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.
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.
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)!
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.
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
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
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.
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.
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 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!
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!
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.
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.
I translate Japanese into English as a side job. The text at 0:23 is a not very good translation from Japanese. A native English speaker has translated this but stuck too close to the wording and sentence structure of the original Japanese. This should have been edited into more natural English. I can totally see the original Japanese sentences, which would sound natural in that language.
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.
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.
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.
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.
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. :)
Removing the 20dB attenuation of the rear inputs can easily be achieved by clipping or soldering a short link wire across the input resistors on whats called the Meter & Microphone Amplifier Unit board in the service manual. Service manual can be had from hifiengine website. AF Oscillator sounds as though the frequency needs adjusting too as my ears can't normally hear 20Khz but I could still hear something when the knob was swept to the high frequencies. The VU meters could probably be brought back into agreement by adjusting the variable resistors R13 and R21 in the driver circuit on the same board that does the input attenuation for the rear inputs..
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
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.
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.
Wow! I just found your channel. This vid is great! When I was a kid we had a Centrex (by Pioneer) integrated stereo (AM/FM, cassette, record player on top) and an external 8-Track player similar to yours (though yours seems to have a few more buttons and whistles). Circa 1977 or '78. Thanks for doing this video. This was very cool. Keep going!
Every time I see Techmoan mute music because of RUclips copywriting I get sad, angry and as a musician I wish I could contribute my music to channels I like so they can play it as much as they want. Cheers, love your channel mate.
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 :(
In my journey of RUclips surfing I found your content to standout and unique combined with great videography. Wow how do get hold of such things, just awesome.
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
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.
if you were to reinvestigate the non pressing issue of the level meters, they have one trim pot each. in the promotional brochure there is the bottom view and they are the two bright things just left to the number 7. the service manual has a short section on meter calibration on page 19.
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
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.
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.
Hooray for Quad! If you need any help with that one be it knowledge, equipment or even some software, don't hesitate to ask! Either I or the Quad community will help you out any way possible. And if I can't help I can certainly point you in the direction of the right fellow. Groovy!
Beautiful bit of kit that :) love the vintage audio. This one is all eye candy. Not only is it lovely to look at, but I'm kind of laughing a bit as it's way more for looks than any sort of serious measurement device. For example, the fact you can adjust the horizontal and vertical gain with a pot rather than in discrete calibrated steps is a dead giveaway :). Not that that matters at all. Same with the oscillator, can't set it to bang on 1kHz, and also - we can still hear the high end, so that is most definitely not going up to 20kHz, pretty much anyone over 30 can't hear that high anyway due to a life of hearing damage just from ambient modern noise. Perhaps that's just a loss of its calibration over the decades (leaky caps etc). Beautiful device, I absolutely agree your setup needed it :D
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.
00:46 - This blurb reminds of of Firesign Theater's Ralph Spoilsport of Ralph Spoilsport Motors: "Right next to the radio, there - completely modulated with dual left and right stereo speakers in two compatible frequencies. "
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.
I have the Kenwood version of this its called KT6000 "Audio Lab scope". It also FM multi-path input for those few tuners that had a multi-path output. Of course the Kenwood KT7000 tuner had this. It also had standard RCA plugs. I believe the Kenwood scope cost around $200. The FM multipath is usefull since it tells you how much direct/reflected signal your picking up so you can orientate the (FM) antennea properly. The only problem with this type of ancient (vintage) equipment is that you need to replace *all* of the electroltyc capacitors (especially the high voltage ones) due to age else it may just start to smoke one day.
I had a quad radial Marantz receiver with an oscilloscope back in the day... loved it (I think it was the 4400) very heavy. Sadly it got away. Ill be watching for your quad review.
16:52 Is that a MiniDisc player in the bottom right corner? Sweet! I thought you didn't have any MiniDisc player hooked up in your system. I love those!
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.

This device makes audio visually pleasing. Superb video.
DR DCC but does it make video audibly pleasing?
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!
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)
Thanks for sharing this esoteric info!!! I love it. And the silver-front design of that era was SOO COOOL
I always enjoy seeing retro devices appearing on your channel, my favourite type of content.
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
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?

"The Techmoan Effect" i love that phrase! :D haha
id try and rig up an oscilloscope to the speaker output.
Absolutely love your videos and your passion for vintage gear, thank you for bringing this gem to life!
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.
Love the new HiFi cabinet, would also love a tour of everything you've got in it!

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!
i really love pioneer electronics man.. and you''re starting to make me like the retro grooves. i have to get one in future God willing

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.

"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".
this is a beautiful piece !
You have a nice set up techmoan, that scope really sets the mood.Cheers
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.

Hands down, one of the best things I've seen and I actually want one. Great video
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.
Beautiful piece of hardware.
What a lovely piece of kit. I think you're going to need a bigger house soon!
Wow i love vintage tech on this channel!
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!

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.
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.
All I'm looking for is a CT-F1000 to join my receiver and then you show this beauty... the hunt has just gotten longer!
Thanks to you, I now have both mailcall devices. My friends love playing with them.
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
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.
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.
I usually only understand about 1/2 or what he's saying..... and yet, these are the most fascinating videos on the internet........
Incredibly informative, excellent video, loving it already and then, bam, you drop some Rob Base in there, and took it up another notch. Excellent.
Love your reviews. Especially old tech. Been a subscriber to your channel for a while now. Awesome content as always
Nice you cover this. Almost bought one a year ago....
This is one of the coolest HIFI accessories I've ever seen
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.
Wow! I just found your channel. This vid is great!
When I was a kid we had a Centrex (by Pioneer) integrated stereo (AM/FM, cassette, record player on top) and an external 8-Track player similar to yours (though yours seems to have a few more buttons and whistles). Circa 1977 or '78.
Thanks for doing this video. This was very cool.
Keep going!
Ich liebe deine Videos über Vintage HiFi, Grüsse aus der Schweitz
I love your videos about vintage HiFi, greetings from Switzerland
I love your system! So organized.
Every time I see Techmoan mute music because of RUclips copywriting I get sad, angry and as a musician I wish I could contribute my music to channels I like so they can play it as much as they want.
Cheers, love your channel mate.
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 :(
In my journey of RUclips surfing I found your content to standout and unique combined with great videography. Wow how do get hold of such things, just awesome.
Now this is something I could just sit and watch all afternoon!
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.
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.
if you were to reinvestigate the non pressing issue of the level meters, they have one trim pot each. in the promotional brochure there is the bottom view and they are the two bright things just left to the number 7. the service manual has a short section on meter calibration on page 19.
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
Beautiful.
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.
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.
Thanks for the Retro Grooves tip! Brilliant!!!
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.
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.
I know dudes being hard-core audiophiles, who would KILL for a unit like this! You sure are lucky, TM!
Hooray for Quad! If you need any help with that one be it knowledge, equipment or even some software, don't hesitate to ask! Either I or the Quad community will help you out any way possible. And if I can't help I can certainly point you in the direction of the right fellow. Groovy!
Oh boy my body just shivered with that sine wave test
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
Wow, what a sweet bit of un-essential kit. Damn, I want one!
Beautiful bit of kit that :) love the vintage audio. This one is all eye candy. Not only is it lovely to look at, but I'm kind of laughing a bit as it's way more for looks than any sort of serious measurement device. For example, the fact you can adjust the horizontal and vertical gain with a pot rather than in discrete calibrated steps is a dead giveaway :). Not that that matters at all. Same with the oscillator, can't set it to bang on 1kHz, and also - we can still hear the high end, so that is most definitely not going up to 20kHz, pretty much anyone over 30 can't hear that high anyway due to a life of hearing damage just from ambient modern noise. Perhaps that's just a loss of its calibration over the decades (leaky caps etc).
Beautiful device, I absolutely agree your setup needed it :D
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.
00:46 - This blurb reminds of of Firesign Theater's Ralph Spoilsport of Ralph Spoilsport Motors:
"Right next to the radio, there - completely modulated with dual left and right stereo speakers in two compatible frequencies. "
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.
Another brilliant review. Many thanks.
I have the Kenwood version of this its called KT6000 "Audio Lab scope". It also FM multi-path input for those few tuners that had a multi-path output. Of course the Kenwood KT7000 tuner had this. It also had standard RCA plugs. I believe the Kenwood scope cost around $200. The FM multipath is usefull since it tells you how much direct/reflected signal your picking up so you can orientate the (FM) antennea properly. The only problem with this type of ancient (vintage) equipment is that you need to replace *all* of the electroltyc capacitors (especially the high voltage ones) due to age else it may just start to smoke one day.
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.
I had a quad radial Marantz receiver with an oscilloscope back in the day... loved it (I think it was the 4400) very heavy. Sadly it got away. Ill be watching for your quad review.
16:52 Is that a MiniDisc player in the bottom right corner? Sweet! I thought you didn't have any MiniDisc player hooked up in your system. I love those!
