I randomly bought a scope today because it looked so nice and 5 hours later I got your video recommend with the exact same scope that's what I call good timing. Thanks for the Videos and sharing your wisdom.
Good job Paul, I vote for a restoration video too! One trick for trace alignment is to leave the CRT collar a little bit loose and slide the case back on (of course that is if you have access to the front of the tube, i.e. no graticule in the way). Then lightly and carefully rotate the CRT from the front until the trace is horizontal. Carefully slide the case off and snug up the collar - makes trace alignment more of a science than an art! ;-) 73 - Dino KL0S
I grew up when these things were for sale and built many a Heathkit. I miss those days. I always learn something like the white getter on the tube and how it works.
The resto has been done. Look for the "i" symbol at the top right of your screen, it will appear in the video about mid way through. Click on that link.
I would watch the restoration. I'm finding I have a bit of the repair bug when it comes to electronics. I like repairing stuff, and watching it be repaired! Especially old kit like this scope. =) I learned quite a lot from your channel, I find I'm learning as much off the internet as I am in my electronics classes in college. =)
1962 high school electronics class. I assembled one of 3 kits the instructor bought for the class. The first one assembled when the instructor turned it on a lot of smoke came out. The kid who assembled it shorted the filament ckt and burned a bunch of paths off the pc boards(took the instructor a lot of time to un do the total damage done, lots of mistakes). When he was ready to test mine. He was nervous and asked if it was going to work. I said:"Oh yee of little faith, of course this one will work perfectly". Turned it on and WooHoo!! it worked perfectly. Lesson was follow the instructions. I am a ham radio/electronics guy and have lots of heath kit stuff. Workmanship is ALWAYS suspect. Most of them had something done wrong(many times I suspect thats why I got the thing so cheap). Loved seeing you video and it brought back memories. Bravo!
I enjoyed the video. My former neighbor was a TV and radio repair person in the 1950s. He gave me his old Oscilloscope many years ago and it has been sitting in my work area for years as a reminder of him and for its impressive looks. I've never applied power to it. After seeing your video I'm tempted to restore it. I would be interested in seeing you do one. Thanks so much for doing these videos. You are the best video instructor on the internet.
Would really like to see you restore the scope... I knew about the tube getter flash when manufactured to remove impurities, but never realized the coating it left behind continued to do so during operation.... this is why I like watching your video's, I always learn something. Thanks, Tom
Hi Paul, I had just been watching you'r rebuild on the Tektronix scope and commented on that and hey presto! you have this video on the old Heathkit scope. This was the first scope that I had. It was a lucky find while I was on holiday at Filey on the East coast here in the U.K. I spotted it on the outside front of a second-hand shop there and paid the great price of £5.0 for it. What a bargain. I remember just doing a quick safety check on it and plugin it in and it worked. When I got back home after the holiday I had hours of fun testing out various pieces of kit and gradually getting round to modifying the scope. Thanks for the video, it brought back some good memories.
You are making such high quality videos, and i really enjoy watching them. So, yes please, i would really like to see you doing a restoration video of a vintage scope!
Thank you Paul for a great video; Yes! I would love to see a full restoration done, this teaches you more how scopes work and most importantly how to repair one.
I had one of these scopes years ago before I got my Tecktronics 535-s6, I had quite a few scops through out the years, all my stuff is gone now but I still have a NLS MS-215. I had to replace the batteries with a gel-cell and it works great, I just pulled it out now and after sitting for a few months I need to charge the battery. Thanks for another great video, good basic tips.
These old scopes were true workhorses and very reliable on a day to day basis. Even though they are only 5 mHz, They are also useful for servicing older tube color TV's I have an old EICO 460 scope which interestingly has a Sawtooth output. I've had the 460 since my early teens. I recently did some repairs on it including replacing the 5UP1 (which was a common CRT for scopes). I vote for showing the restoration. I wish I had more time to create my own videos, but with a busy shop, it becomes difficult. Also, you may want to show the calibration procedure in a different video after the restoration. I had to re-cal my 460 after the repairs. especially since I replaced most of the existing resistors and caps. Keep 'em coming! You have a following of professional technicians peeping your videos! ::) Frank Ferraro--Audio Craft Electronics.
Hi! I personally enjoy a lot watching your old equipment videos, I think old stuff have a *magical* touch, a mix of nostalgia and the "good-old fashioned rugged stuff" feeling. Keep 'em coming!
Hi Paul, I love the old Heathkits. Enjoyed your restoration video and I certainly would appreciate a further video on the restoration process. I own a lot of the older heathkit and eico pieces of test equipment and they are very easy to service but for the most part are very reliable. Thanks again for your most informative videos By the way the hint on soldering to batteries in your previous video was excellent advice. Don
I put together a Heath O-10 back in the 70's, and it worked great. Unfortunately I lent it to a friend, and it came back broken. Wish I still had it. Would really like to see you put the O-11 back in service!!
Hi. Another excellent video from you. As I just have started with tube type equipment (the restauration of a 1949 commercial german radio just started on my bench) I was already on my way to get something similar as the Heathkit you have there. So I am definitley interested in.the restauration... Go on with your channel, I really enjoy all of you work there. Regards from Munich. Thomas
A restoration video of the Heathkit would be a informative watch to anyone interested in restoring ANY valve based gear. Look forward to it. Big Thumbs Up.
Hi Paul, because of you, I have gotten back into electronics. I built a lot of Heathkits in the 70's and I like this one. A suggestion on aligning the crooked line on the screen is to use a pencil and mark the line on the screen, turn the unit off, open it back up and rotate the CRT to level the pencil line. I really enjoy your resto's.
I will look forward to seeing you rebuild the heathkit notice the caps made in usa and valves made in great Britain I made a oscilloscope some 40 years ago from a kit only sorry i binned it many years ago I could kick my self now. love your videos Paul.
I have an old RCA WO-33 that is in the process of restoration and and Eico 460 that has a short somewhere that I have yet to discover. Gotta love the old gear to work on it and I enjoy all of your videos greatly. Thanx~Ed Allen~N4TYX~
For me personally, it's not that I have interest in old oscilloscopes, it's that I enjoy the way you repair/restore/align/calibrate/improve older vacuum tube devices of any type. I would enjoy seeing the restoration for those reasons. Thank you, Mr Carlson, for your high quality content.
I built one of these in my youth. After building and checking carefully I powered it up and to my horror smoke poured off a large green power resistor. I spent two days going over the circuit and connections. Never found any faults. I eventually just switched on again, the same resistor smoked just a little but all was working fine. I guess it was the paint on the resistor or a little oil maybe getting hot. Scary at the time!! A good little scope, used it for many years without any faults.
You continue to amaze me.I love your videos. I built a lot of heath-kits, I also repaired a lot of them. It always amazed me how some people would screw them up at build time and it would still work(sort of).
I am an owner of that very same scope and it was left to me from my late Grandfather. Actually I just fixed up a Heathkit AG-8 audio generator and V7a tube voltmeter also left to me by my Grandfather. So, coincidently, the Heathkit 0-11 is next in line and I will follow along with your follow up videos to compare the restoration process.
l like watching any old test gear being restored so a big yes please from me. I've got quite a few bits of the UK versions of Heathkit gear which still get used in radio repair. Don't forget that wobbulator you had either! Love to see that one fixed up :) Thanks - Andrew
Paul, A video on restoring that old Heathkit would be interesting to watch. I built a Heathkit Vectorscope to help in adjusting one of their kit color tv's I assembled. I was basically a Zenith in kit form. Worked well for a decade.
Yes on the rebuild video, it might make me brave enough to start on own 1971 Heathkit scope. I brought it up slow on a "variac" and got a trace on the crt, YEAH! The trace dot is the size of a dime however. I guess I'll start with the caps. Thanks for the great work.
I recently found this channel, and its been very informative. This scope looks similar to my RCA wo-78a. It was given to me. I only tinker with electronics occasionally and can not justify the price of a newer scope. It is in need of repair. If you do choose to video the restoration I would benefit greatly. The videos you publish are very well organized and professional. Thank you. This is KD5NBZ.
Another vote for a restoration. You have the best instructional videos on the net. Two big thumbs up! I still have an old Heathkit IO-18 scope. I use a Tektronix 2215A I got at a hamfest now, but I used that old Heath for many years. It probably needs a good going through.
+zaprodk I agree, people always want the modern stuff, but the older stuff you can get for a LOT less is much better made, more servicable, etc. Unless you're testing modern digital high speed gear, there's no need for it
My dad had one of these back in the 1950-60s, he always told me it was not a great scope but it was cool. I have that model sitting in my workshop which came from a estate but it is far gone (looks hit it was hit by a truck). I would enjoy a restore video on this model for sure.
When I was a kid, I rigged up an old Eico 435 to watch TV by running the vert and horix waveforms into the respective inputs and ac coupling the TV CRT cathode to the intensity modulation. I did get inverted black and white (actually, green and white) picture, tho. But I was 11 years old. I thought it was cute.
I am interested in seeing a vintage scope restoration video. I would also like to see a video illustrating proper techniques for handling high voltage, especially the correct techniques for discharging capacitors.
I am so excited. I have the exact scope and have done all the electrolytic caps prior to discovering this video. Ready to dive in to your restoratio of it THANK you so much
Yes, I would like to see the restoration process on this O'scope. Many years ago, while studying with DeVry Technical Institute, I had to build their version of the vacuum tube O' scope. This would be like de ja vu!!
As a teenager I had a similar IO-12U model, which had a bad mains transformer. Someone kindly rewound the transformer and it worked, but there was a bit of hum deflection on the display. I reduced this a lot by making a tube shield from some mu-metal salvaged from an old TV. I used that 'scope for many years before selling it back in the 90s. Hopefully it still works today. As you say, they can't really be used for proper measurements, and being AC-coupled only was a limiting factor.
Wow, that looks a lot like my old Knightkit o'scope that I restored. Actually... after watching the video it's almost exactly like my old Knightkit except yours is very clean and was well taken care of. Mine was a basket case that I basically "dekitted" and started from scratch. I enjoyed every second of the process. I have a stack of scopes to tackle one day. I have a gorgeous Tek 545B that I can't wait to work on. Its so big I have to wait until I get a larger bench. Patience is a virtue right? Fun project! I'd be very happy to see your restoration process.
I built 3 of these at work my awesome friend. YES PLEASE! Show us the restoration. It will be like going back in time. I was 19 when I built them. I am now 66. So YES PLEASE!
I would like to see the rebuild. I have one myself, I built back in 1965. And it needs a rebuild as well. Hard time trying to find HV caps. So as usual great video. Also I am working on a TEK 2430 scope. thanks again, keep them comming. Greg
I like it. I would be most interested in seeing a full restoration. I think it is good for technicians to have a deep understanding of older technology. I worked with some tube equipment in the military, without really understanding how it worked.
I really enjoy your videos especially about rebuilding tube type components. I am starting my first boat anchor restore on a sx-28 and need all the input I can get. Keep them coming. You are very good at this and we newbies need it. Thanks Ken - W0KRD
Hey Mr Carlson, love all these videos on antique and obscure bits of gear (that Tesla coil of yours is great!)... slowly after watching these videos I'm getting what all the componentry and design contributes to the overall, just struggle a bit with putting it all together though!! Anyway appreciate the time and effort you put into these videos, thanks!
I have almost the same scope. Had it since I was a kid. I was going to just use it as a shop ornament, but you have inspired me to try to make it work. I would LOVE to see the restoration video!
I like the video. I recently got a Telequipment Serviscope S32A that I am planning on restoring. I would like to see you do a restoration video on this one to kind of see where to go and what to look out for. Keep up with the great work.
Wow, did you ever do a rebuild video? I'd like to see it. I got a hold of a 10Mhz Heathkit scope in the form of parts and directions. When I built it, All I had was a dot in the middle of the screen. I called the manufacturer. In the end, they provided no answer. They said they remembered that the scope had 3 Engineering chances over time. Traces needed to be cut, parts swapped, etc. But no one seemed to recall what changes were required and they had no supporting paperwork on the mods. I ended up giving the whole thing to a local TV repair shop. I know that the engineering changes were related to the sweep circuits but I cant recall anything beyond that. I really enjoyed this video. Thanks for sharing.
Thanks for the fine run thru. Your comment on the "vintage" poly caps is most useful, that would explain some issues I've had on some other gear.... I just assumed they would not leak. As usual, find your videos through and well produced. Would look forward to a restoration video on this unit.
I've got a couple old Eico scopes that I'd like to get into service for tube radios and amps.Hope you show some of the more important restoration tips and more importantly,how to use it properly and make probes that were not there when first found. Great job on your videos,Paul.Thanks,Art in Victoria,B.C.
Sure, I'll gladly watch more of the restoration, I am really thinking of buying a scope like that as I do not need much more for now at least... Thanks for making this!
Yes Paul, I think would be interesting and could apply this to other brands of scopes that i might wonder into.I did enjoy the Video and yes sure would like to see the restoration . Again like always Thanks for your Efforts and info Paul 73's Dale
I really enjoyed this video and also the restoration video that followed. As a result I picked up one of these and looking forward to getting it back to a like new condition. I've picked up a few items to restore, that you have videos on. I would always vote for a full restoration video of a piece of equipment. One thing I've noted is that if someone powered up a piece of equipment with bad caps, it may cause the power transformer to create 'magic smoke'. Do you ever first check the power transformer, before beginning a restoration? After watching some of your videos I thought it a good idea to do so, especially with the expense of caps and other parts these days, just disconnect the output circuits and make sure the voltages are satisfactory prior to doing a full restoration. So far I've not found a bad power transformer, but must admit I'm just beginning the fun and exciting restoration of old equipment. As always, thanks Paul!
I randomly bought a scope today because it looked so nice and 5 hours later I got your video recommend with the exact same scope that's what I call good timing.
Thanks for the Videos and sharing your wisdom.
I'll join the crowd and vote to see the restoration as well!
My vote is in, inspiration to restore an old Watermans pocket occiliscope
I for one would enjoy seeing a rebuild. My O-12 is due as well, it's going on 57 years old!
I always enjoy restoration videos on the old stuff Paul. Count me in. 73, Bill.
I would like to see your step by step restoration, Excellent video. Two thumbs up!!
+Walt Anderson Me too!
+KG7UJH Yes definitely but we also want military class vobulator rebuild..
Good job Paul, I vote for a restoration video too! One trick for trace alignment is to leave the CRT collar a little bit loose and slide the case back on (of course that is if you have access to the front of the tube, i.e. no graticule in the way). Then lightly and carefully rotate the CRT from the front until the trace is horizontal. Carefully slide the case off and snug up the collar - makes trace alignment more of a science than an art! ;-) 73 - Dino KL0S
Hi Paul, I really like this old stuff and would like the restoration! Great video as always..Take care and 73
I'm with the "Yes" crowd on the rebuild!
I grew up when these things were for sale and built many a Heathkit. I miss those days. I always learn something like the white getter on the tube and how it works.
My favorite part of this video is "The Magic Smoke". I've witnessed this phenomenon occur a few times! And yes, please make a restoration video.
I always enjoy watching your restoration videos. I had one of these scopes but disposed of it about 15 years ago. Now I wish that I had kept it!
Do it, rebuild, repair it!!! I'd love to see a restoration of it!!!
The resto has been done. Look for the "i" symbol at the top right of your screen, it will appear in the video about mid way through. Click on that link.
I would watch the restoration.
I'm finding I have a bit of the repair bug when it comes to electronics. I like repairing stuff, and watching it be repaired! Especially old kit like this scope. =)
I learned quite a lot from your channel, I find I'm learning as much off the internet as I am in my electronics classes in college. =)
I have aquired a Heathkit O-10 Scope so now ,yes I would love to watch the complete rebuild.
1962 high school electronics class. I assembled one of 3 kits the instructor bought for the class. The first one assembled when the instructor turned it on a lot of smoke came out. The kid who assembled it shorted the filament ckt and burned a bunch of paths off the pc boards(took the instructor a lot of time to un do the total damage done, lots of mistakes). When he was ready to test mine. He was nervous and asked if it was going to work. I said:"Oh yee of little faith, of course this one will work perfectly". Turned it on and WooHoo!! it worked perfectly. Lesson was follow the instructions. I am a ham radio/electronics guy and have lots of heath kit stuff. Workmanship is ALWAYS suspect. Most of them had something done wrong(many times I suspect thats why I got the thing so cheap). Loved seeing you video and it brought back memories. Bravo!
+NebukedNezzer Yes the scope I assembled for high school electronics lab was the same model.
I enjoyed the video. My former neighbor was a TV and radio repair person in the 1950s. He gave me his old Oscilloscope many years ago and it has been sitting in my work area for years as a reminder of him and for its impressive looks. I've never applied power to it. After seeing your video I'm tempted to restore it. I would be interested in seeing you do one. Thanks so much for doing these videos. You are the best video instructor on the internet.
Would really like to see you restore the scope... I knew about the tube getter flash when manufactured to remove impurities, but never realized the coating it left behind continued to do so during operation.... this is why I like watching your video's, I always learn something. Thanks, Tom
Hi Paul, I had just been watching you'r rebuild on the Tektronix scope and commented on that and hey presto! you have this video on the old Heathkit scope. This was the first scope that I had. It was a lucky find while I was on holiday at Filey on the East coast here in the U.K. I spotted it on the outside front of a second-hand shop there and paid the great price of £5.0 for it.

I had one of these scopes years ago before I got my Tecktronics 535-s6, I had quite a few scops through out the years, all my stuff is gone now but I still have a NLS MS-215.
I had to replace the batteries with a gel-cell and it works great, I just pulled it out now and after sitting for a few months I need to charge the battery.
Thanks for another great video, good basic tips.

Please do this restoration. Your repair and mod work is why I subscribed.
Hi. Another excellent video from you. As I just have started with tube type equipment (the restauration of a 1949 commercial german radio just started on my bench) I was already on my way to get something similar as the Heathkit you have there. So I am definitley interested in.the restauration... Go on with your channel, I really enjoy all of you work there.
Regards from Munich. Thomas
A restoration video of the Heathkit would be a informative watch to anyone interested in restoring ANY valve based gear.
Look forward to it.
Big Thumbs Up.
Hi Paul, because of you, I have gotten back into electronics. I built a lot of Heathkits in the 70's and I like this one. A suggestion on aligning the crooked line on the screen is to use a pencil and mark the line on the screen, turn the unit off, open it back up and rotate the CRT to level the pencil line. I really enjoy your resto's.
I certainly hope that you’re still working with the old O’scopes. I have 3 but only one works. I absolutely love working with the old radios and such.
I will look forward to seeing you rebuild the heathkit notice the caps made in usa and valves made in great Britain I made a oscilloscope some 40 years ago from a kit only sorry i binned it many years ago I could kick my self now. love your videos Paul.
Great trailer - I will wait along with the rest of the gang for the main show - please.
I have an old RCA WO-33 that is in the process of restoration and and Eico 460 that has a short somewhere that I have yet to discover. Gotta love the old gear to work on it and I enjoy all of your videos greatly.

Yes on the rebuild video, it might make me brave enough to start on own 1971 Heathkit scope. I brought it up slow on a "variac" and got a trace on the crt, YEAH! The trace dot is the size of a dime however. I guess I'll start with the caps. Thanks for the great work.

Thank you so much for your succinct video on oscilloscope steps for restoration. I learned some highly usable things here!
Your welcome!
Another vote for a restoration video, Paul. The price for hamfest scopes is sure to rise as a result!
My dad had one of these back in the 1950-60s, he always told me it was not a great scope but it was cool. I have that model sitting in my workshop which came from a estate but it is far gone (looks hit it was hit by a truck). I would enjoy a restore video on this model for sure.

Your welcome Blair!
I like watching your restoration videos. They go to the heart of what I like to do. Thanks Paul!
I have just started to restore an IO-12, so this video is perfect for me.
Yes, I would like to see the restoration process on this O'scope. Many years ago, while studying with DeVry Technical Institute, I had to build their version of the vacuum tube O' scope. This would be like de ja vu!!

I really like the restoration mr Paul. Great stuff,
I built 3 of these at work my awesome friend. YES PLEASE! Show us the restoration. It will be like going back in time. I was 19 when I built them. I am now 66. So YES PLEASE!
I'm going to vote to include the video on the restoration process. Thanks Paul
Ofcourse I love to see the restoration of this beautiful piece of technical history! And I'm going to watch it right now...
I would like to see the rebuild. I have one myself, I built back in 1965. And it needs a rebuild as well. Hard time trying to find HV caps. So as usual great video. Also I am working on a TEK 2430 scope. thanks again, keep them comming. Greg
I like it. I would be most interested in seeing a full restoration. I think it is good for technicians to have a deep understanding of older technology. I worked with some tube equipment in the military, without really understanding how it worked.
I`d be very interested in seeing more of this old stuff! Watching this restoration would be great! Thanks!
Love to see more on the scope. Thanks.
YES, please rebuild the Heathkit O-11 scope. Thank you.
I love these kinds of videos, Mr Carlson of,Mr Carlson's Lab is Brilliant!!!
Of course...we want to see you rebuild this scope. This is unique and your take on how to approach it would be awesome!
Count me in for wanting to see a restoration video as well. Thanks
I really enjoy your videos especially about rebuilding tube type components. I am starting my first boat anchor restore on a sx-28 and need all the input I can get. Keep them coming. You are very good at this and we newbies need it.
Thanks

Thanks Ken. I will doing an in depth video on that receiver in the future.
Would indeed like seeing the restoration!
I would also like to see the restoration, you explain very well and the footage is always perfect.
Thumbs up, as always. :)
Hey Mr Carlson, love all these videos on antique and obscure bits of gear (that Tesla coil of yours is great!)... slowly after watching these videos I'm getting what all the componentry and design contributes to the overall, just struggle a bit with putting it all together though!! Anyway appreciate the time and effort you put into these videos, thanks!
I have almost the same scope. Had it since I was a kid. I was going to just use it as a shop ornament, but you have inspired me to try to make it work. I would LOVE to see the restoration video!
I absolutely would like to see the restoration!
Paul. I always enjoy watching you at work. I have an old Philips scope so would like to watch along as you fix this one up. Keep em coming. Graham
I like the video. I recently got a Telequipment Serviscope S32A that I am planning on restoring. I would like to see you do a restoration video on this one to kind of see where to go and what to look out for. Keep up with the great work.
I'm onboard. That thing is gorgeous .
Nicely done. Yes you should record the resto on the scope.
Wow, did you ever do a rebuild video? I'd like to see it. I got a hold of a 10Mhz Heathkit scope in the form of parts and directions. When I built it, All I had was a dot in the middle of the screen. I called the manufacturer. In the end, they provided no answer. They said they remembered that the scope had 3 Engineering chances over time. Traces needed to be cut, parts swapped, etc. But no one seemed to recall what changes were required and they had no supporting paperwork on the mods. I ended up giving the whole thing to a local TV repair shop. I know that the engineering changes were related to the sweep circuits but I cant recall anything beyond that. I really enjoyed this video. Thanks for sharing.
engineering changes, not chances.
I'm ready to see the rebuild I enjoy the older stuff really cool. Thanks for sharing.
Thanks for the fine run thru. Your comment on the "vintage" poly caps is most useful, that would explain some issues I've had on some other gear.... I just assumed they would not leak. As usual, find your videos through and well produced. Would look forward to a restoration video on this unit.
I've got a couple old Eico scopes that I'd like to get into service for tube radios and amps.Hope you show some of the more important restoration tips and more importantly,how to use it properly and make probes that were not there when first found. Great job on your videos,Paul.Thanks,Art in Victoria,B.C.
Yep! This has got to be done.
I would love to see the full restoration. I have an old Dumont that i want to restore and this would help out a bunch!
Sure, I'll gladly watch more of the restoration, I am really thinking of buying a scope like that as I do not need much more for now at least...
Thanks for making this!
Yes Paul, I think would be interesting and could apply this to other brands of scopes that i might wonder into.I did enjoy the Video and yes sure would like to see the restoration . Again like always Thanks for your Efforts and info Paul 73's Dale
Yes please I would very much like to see the restoration.
Yes, I'd like to see the rebuild/restoration.
Yes, I would like to see the restoration.
I have a scope like this and would love to see a restoration of one. Thanks!
Very interesting. MORE vintage stuff, please!
I really enjoyed this video and also the restoration video that followed. As a result I picked up one of these and looking forward to getting it back to a like new condition. I've picked up a few items to restore, that you have videos on. I would always vote for a full restoration video of a piece of equipment. One thing I've noted is that if someone powered up a piece of equipment with bad caps, it may cause the power transformer to create 'magic smoke'. Do you ever first check the power transformer, before beginning a restoration? After watching some of your videos I thought it a good idea to do so, especially with the expense of caps and other parts these days, just disconnect the output circuits and make sure the voltages are satisfactory prior to doing a full restoration. So far I've not found a bad power transformer, but must admit I'm just beginning the fun and exciting restoration of old equipment. As always, thanks Paul!
These brown PCBs in Heathkits are my favorite.
Yes, one of my favorites. All if your videos are top-notch. Many thanks!
