Amusingly, if someone had bought one of these to learn with, having so many faults, they would be a master electronic engineer by the time they’d fixed it!
I have a similar problem with an HP8008 pulse gen, it seemed to work fine when put in my makeshift tracer at 100kHz, but it didn't work in the circuit at a couple hundreds of MHz equiv. That Pulser has been keeping me busy and confused for months now. The golden HP mystery ICs don't help either.
You know you have one of the most intense breadboards on the planet when you need elevator music! Excellent effort and good to see this unique piece back in service!
All things equal, as a test rig for learning or prototyping, to this day that unit would be amazingly useful. I can think of a million examples as a kid teaching myself electronics, when that unit would have been an absolute god send!
HI Marc I am an HAM operator from switzerland and doing my best to understand electronics. I really, really loves your video! Great job! I hope we can drink a coffee toghether, when I am the next time in the US? Kind regards Simon
Whoooooooa. The way this device is built is an absolute gorgeousness. Big kudos to Mr Ken for the reverse engineering. I like your lab coats BTW, doing science with style. I love the old electrolytics. They look so nice and if they weren't kept in bad conditions, will be fine. And the core memory is a joy for ever.
Congrats on the success of the restoration and thanks for the insight on the oscillating circuit! I sure learned something :) And thank you so much for taking us on your repair-adventures for so many years now! It is really something to look forward to every time!
Another fantastic achievement! About BNC’s: I’ve straightened a few by machining a sort of bronze bush with its outer dia as the inner of BNC (a central hole need to have room for the hot contact clearly) and plugging it with some force. Few external tapping with plastic hammer refine the trick. The insertion side of the bush should have a good chamfer.
These vids are so much more entertaining and educational than all NCISNYCSI acronym TV "detective" stuff put together. I was on the edge of my seat all the way to when he found culprit in the slow transistor - PHEW! Great video, but who expects other than greatness on this channel👌
Cost new today was originally ~$10K in todays value. After you and crew get done with it and I get the bill back from the repair shop, well over $50K dollars mostly from time and talent! And yes, mismatched switching speeds would have stumped me to the point of just saying don’t go past 30 MHz or whatever it was. :)
Thanks a lot for all the videos you do, i have learned so much about troubleshooting from you. Love the "antique" technology it always seems more appealing than modern equipment. The build quality is often way better than the more modern stuff i have. Take care.
Happy to see this beautiful machine working again, when I was little I remember having seen the micro-professor MPF-1, the E&L CADET series, expensive equipment, that's why I barely had the opportunity to acquire two DD-1, an OA-1 in the form of kit but without an assembly manual and several bugbooks, don't hesitate, they are still in use but it cost a lot to make them work due to the lack of information in a time before the internet. E&L manufactured excellent quality products with well-known brand components and military-type finishes.
Congrats on getting the unit working again. Your tenacity is exemplary, and having some great friends to bounce ideas off is so awesome! It is so easy to lose the will to live looking at some analog circuits but as you've shown slowly and carefully breaking down what they do reaps rewards. Another awesome repair.
Well done! Enjoyed this series. Encouraged me to get my breadboard out and hook up an old Z80 CPU. Wish I had that "contraption" for my clock instead of a 555!
Brilliant diagnostic of the oscillation fault! That turn on/turn off time is not something that gets taken into consideration very often. I like the fix for it by just reversing the positions of the the 2 transistors. Thanks for showing this! I seem to be learning something new quite often watching your videos. :)
A lot of faulty components, but then again, there are quite a few components needed to make up the whole contraption so in percentage it wasn't bad. I'm not an experienced electronics guru, it was a couple of decades ago I worked in electronic design, but I am amazed that the big caps were just fine😮
Amazing piece of work finding that switching speed problem with that transistor - which is still puzzling because the data sheet puts it in spec. range but its actual operation is a bit slower,,, I guess that can happen obviously,,, first time I have ever seen something like that and amazing skills to find it which probably would not have happened without a good scope and more importantly knowing what you are looking at on it !!!!!! - Hence,,, a perfect video for showing the power of a good scope and how to read it !!!! Made My Day, and I learned something I would have probably never found - until now,,, I will never forget this - Thank You !!!!!
Great repair! PS: I had the subtitles left on from another video... I didn't realize you made them for your videos! I'm sure those that need them find them quite helpful.
With those giant filter caps hanging off the bridge rectifiers, I bet the turn-on surge eventually killed that one rectifier. Next time you have it opened up, might be worth adding some kind of inrush protection on all those supplies... Good catch on the buffer transistors! BTW, in the 70's as a middle-school kid, I could only look at ads for things like this and drool over it. Even the plain old Continental Specialties breadboards of the time (with no power supply or other circuitry) were kinds spendy....
What a fascinatingly complex piece of equipment! I'm amazed that there was ever a market for such a thing, as you'd have thought that anyone who could afford it would probably have had all the required equipment on hand anyway. It's fantastic that you're preserving these things, and keeping the technical knowledge alive.
I suspect they were mostly sold to companies to save time on prototyping, rather than a hobbyist. Especially with those high reliability lamps having their own driver circuit instead of feeding them the AC directly. A hobbyist can wire up the switches and lamps ourselves! But speeding-up the build and teardown time could save a company a fair bit on development budgets. That’s just my supposition though, I haven’t looked into it. Maybe they really were just sold to rich kids!
What an absolutely devious fault with the comparator buffers. I'm pretty certain I would have never figured that one out no matter how long I puzzled over it.
You can also prevent transistor saturation with Schottky diode from base to collector to speed up turn-off time. 74Sxx and 74LSxx logic use this trick.
Nice repair and great video series, thank you for sharing it with us. I am currently repairing an HP 8165A Signal Source that uses the same sine shaper circuit - an elegant HP design - simple and effective.
Gosh, what is it about breadboards that make them so cool...? Especially this one with all the lights, knobs, buttons, and dials. This would have been a lot tougher to fix without a great stash of parts. Thanks for a truly enjoyable video project. It is very much appreciated.
11:00 my immediate thought was that the hot comparator was supposed to have a heatspreader like the ones on the other side of the board, but it was apparently something far more devious
Well done..! I have quite a few of those breadboard sockets from the previous century here too. Wondering how well the internal contacts hold up, and anything you might have learned about magic restorative potions that might be beneficial....
That is an odd circuit design for the oscillator there. I would have expected the output into the integrator to have been fed off the feedback to generate hysteresis, so that sort of speed mismatch wouldn't matter. Instead they split the path two ways so it's sensitive to such variations. I wonder why they did that
Likely they wanted to buffer the paths so the input bias of the comparator (which could be quite hot for high speed) wouldn't affect the impedance going into the integrator (which could make it asymmetrical)
It would be interesting to put the sinewave on a FFT 'scope or spectrum analyser to see how pure it is. As you say, not HP quality, but I wonder how it would compare.
I watch hours of your videos. Hours. And I don't even understand half of what's going on. And the other half I also just pretend. But I still feel like I learn something. I think I would've watched these videos as a kid as well.
Three fun debugging sessions. Filming a screen with a circuit diagram on it, and pointing at it, leaves the circuit rather hard to read. I'd prefer you to use video screen capture and point with the cursor, although I accept that is more work.
True, but then you don’t get to follow the live debug process, which is the whole point of the videos. Also the full hi-res schematics are available at the link in the description.
Amazing, that some electrolytic caps last forever and some don't. I collect old audio gear and I try to keep things I don't use daily/commercially, original. I own a lot of stuff from the 50s and 60s with perfect electrolytics. Even the dreaded mallory and sprague caps in the cardboard tubes hold up more often than not. The only electrolytics that really suck in my experience are small voltage ones from the 60s and 70s and the cheap crap in 60s TV sets, which goes open because the connection strips between the terminals and the capacitor roll get eaten away.
"Hey it works better when joined with solder" Yeah I haven't had much luck with those air-gap diodes either. Least not at the voltages I usually deal with. Perhaps one of you HV magicians know of air-gap diodes that work without solder!
It's not that unusual. The output of the comparator is a digital signal. And fiddly elusive logic races are a clasic fault of digital circuitry :) But I appreciate it was hard to spot!
In particular, a classic fault of digital circuitry the design of which, shall we say, leaves a lot to be desired. "This won't matter because the other path is supposed to be slower" is not a valid design mindset.
I hate transistors. I still have nightmares from when I used to have to service and repair EG&G (subsea) side-scan sonar systems. Not just resonant signal generators, but time-variable gain circuits with feedback, all built using discreet components on a packed PCBs that had been treacled in conformal coating. Then the joy of not fitting an O-ring correctly, so that the entire electronics module would flood with sea-water and flash 500v across every transistor and diode I'd spent twelve hours replacing. Happy days
@@1pcfred Yes but gold plate or not they will all need cleaning, at least a scrub with a new toothbrush and cleaner to get the dirt out of the cervices, then a further rinse to get the stuff out from inside. Probably best to do this with the unit upside down so the dirt can drain out with the wash. Pump action bottle with alcohol works best there, lots of rinse needed, and the first one or two will be dark with dirt.
Hi Mark, I noticed that you updated master Ken’s schematics and fixed some of the NPN and PNP error’s.. would it be possible to update original schematic on the master Kens blog ? Also, is there a component map that corresponds with the schematic numbering ? Thank you !!
It’s designed like an “escape room.” You’re not supposed to solve the riddles in a few minutes. So… $1300 for, what, a few hundred hours cumulatively of entertainment? Makes it starting to sound reasonable.
Another great restoration and a good inspiration to build a similar unit. Does anyone knows were to find those female, panel mounted, jumper wire connectors?? Already looked around, but could not find anything similar, just the regular wire mounted ones, which could work, but I bet not for a long time.
Great Tool, never seen it before - now I want to have one. BTW, How do you store, sort und find your Components and IC´s ? Do you have a database, how critical is ESD at storage ? Would be great if you make a Storage Tour Video :-) Best Regards, Asd
Lots of upfront work, but an unsorted and non inventoried collection of parts is as if you had no parts at all. I research each component, put in its own little bin with a label that includes all the important parameters. But then all I need to do, is go to the PNP section, and scan for a 60V 250MHz 500 mW or thereabouts, and voila!
Amusingly, if someone had bought one of these to learn with, having so many faults, they would be a master electronic engineer by the time they’d fixed it!
OMG that slow transistor would have totally stuffed me. Well done indeed.
I have a similar problem with an HP8008 pulse gen, it seemed to work fine when put in my makeshift tracer at 100kHz, but it didn't work in the circuit at a couple hundreds of MHz equiv. That Pulser has been keeping me busy and confused for months now. The golden HP mystery ICs don't help either.
You know you have one of the most intense breadboards on the planet when you need elevator music!
Excellent effort and good to see this unique piece back in service!
Thanks David. And with two 35V supplies, I could almost do tune circuits like someone I know. Even Nixies, if I can strike them with 70V!
All things equal, as a test rig for learning or prototyping, to this day that unit would be amazingly useful.
I can think of a million examples as a kid teaching myself electronics, when that unit would have been an absolute god send!
The "COMPUTER GRADE" capacitors with screw terminals are amazingly good.
HI Marc
I am an HAM operator from switzerland and doing my best to understand electronics. I really, really loves your video! Great job! I hope we can drink a coffee toghether, when I am the next time in the US?
Kind regards

9:32 Right you are, Ken. Right you are.
Ken was observing from a safe distance (A-L-W-A-Y-S)
Incredible work! I would have never worked out that transistor issue causing the oscillation!
Whoooooooa. The way this device is built is an absolute gorgeousness. Big kudos to Mr Ken for the reverse engineering. I like your lab coats BTW, doing science with style.
I love the old electrolytics. They look so nice and if they weren't kept in bad conditions, will be fine.
And the core memory is a joy for ever.

And thank you so much for taking us on your repair-adventures for so many years now! It is really something to look forward to every time!
Another excellent presentation. Your explanations are worth half-a-dozen textbooks.
Nothing beats Marc's elevator music interludes, with schematics!
Another fantastic achievement! About BNC’s: I’ve straightened a few by machining a sort of bronze bush with its outer dia as the inner of BNC (a central hole need to have room for the hot contact clearly) and plugging it with some force. Few external tapping with plastic hammer refine the trick. The insertion side of the bush should have a good chamfer.

Agreed. I had to take a break in the middle because the suspense was killing me!
Cost new today was originally ~$10K in todays value. After you and crew get done with it and I get the bill back from the repair shop, well over $50K dollars mostly from time and talent! And yes, mismatched switching speeds would have stumped me to the point of just saying don’t go past 30 MHz or whatever it was. :)
I love Master Ken's white lab coat!
Thanks a lot for all the videos you do, i have learned so much about troubleshooting from you. Love the "antique" technology it always seems more appealing than modern equipment. The build quality is often way better than the more modern stuff i have. Take care.
Was really fun to watch. Tiny SMD electronics would be much harder to repair.

I just love these. I don't do anything electronic but this stuff is fascinating.
I think this breadboard will live to tell the tales of future interesting stuff going on in this lab. Thanks Marc!
Excellent job, Marc, thank you for this miniseries. I think I need a powered breadboard now.

Glory to the repair Team A!
Was anyone else like: oh good, master Ken is there, and Eric, now they will for SURE fix it with their combined powers of deduction.
What a cool device! It is neat to see it operate as intended.
What an absolutely devious fault with the comparator buffers. I'm pretty certain I would have never figured that one out no matter how long I puzzled over it.

You can also prevent transistor saturation with Schottky diode from base to collector to speed up turn-off time. 74Sxx and 74LSxx logic use this trick.

Lol Ken. I think they were kicking in too.
Well done to the dream team!
The board is very clean condition !
I stay tuned.
I'd been wondering, and yes you are using 1161A probes, they're so much nicer than the basic ones, especially if you have the full accessory kits.
It’s too bad they don’t make these anymore. They are indeed far better than the modern ones. But much more delicate too.
@@CuriousMarc yeah, great for a personal bench, not ideal for shared labs.
11:00 my immediate thought was that the hot comparator was supposed to have a heatspreader like the ones on the other side of the board, but it was apparently something far more devious
I have done a stupid thing and purchased an elite 2 from eBay , let the vintage breadboard goodness begin!
You’ve done the right thing!
We did it! Great work team.
Papa, mama and baby breadboard!! Brilliant, I missed the classic title on first view!!
It's alive!
Great troubleshooting. That's a lot of bad components. I salute you sir, for your perseverance..
Looking forward to the monster breadboard system adding some "interesting distractions" in a future episode! 😜

And you can see they struggled with it too, there are little caps added here and there to tweak the timing.
Maybe trying to not copy the HP (patented?) so blatently.
Likely they wanted to buffer the paths so the input bias of the comparator (which could be quite hot for high speed) wouldn't affect the impedance going into the integrator (which could make it asymmetrical)
It would be interesting to put the sinewave on a FFT 'scope or spectrum analyser to see how pure it is. As you say, not HP quality, but I wonder how it would compare.

I hope you didn't throw those valuable oval BNC sockets out, you'll regret that when you need one to match an oval plug.
check the fuses on the back of the unit. A dead short on the transformer should have blown the corresponding fuse.
It did not, I suppose because it was just one diode on one winding, and the fuse must have been a bit oversized indeed.

Not gonna lie I want to make something like this now, but with more modern modules.
Breadboard with built in i2c decoder? Don't mind if I do lol
Great job. What do you think caused the transistors to fail? Time? the power supply? Gravity?
Those epoxy drop transistors just suck. Moisture gets in over time.
I do not know. I would be interesting to find out by chemically removing the Glob Top.
It's a good job you bought it. I pity anyone else
Wonderful stuff ❤️
I half expected the power supply to have blown out all those transistors you replaced when it was making that noise lol.
I love those series :D Great explanation! Congratulation for success ;)
I'm glad you haven't replaced any capacitors. That would be a crime.
Next up cleaning all the breadboard contacts, because they will all be very dirty. Tuner 600 to the rescue, or Electrolube WL.

A before B except after C. what a bitch of a fault to find. it reminds me of a few SMPS i have come across over the years.
(20:14) " FULL BRIDGE Rectifier!" -- Mehdi Sadaghdar ElectroBOOM!
So did you check THD on that sine generator? It didn't look all that bad visually.
Yes, this was adjusted for minimum THD using the spectrum analyzer. This diode circuit is surprisingly good, less than 1% when properly adjusted.
7:50 Avengers, assemble!
"hey, it works better when joined with solder!"
😂
It’s no longer a diode bridge; it’s a diode overpass. But it doesn’t have enough clearance to let the trucks (electrons) pass, so big crash. 😢
Eric, get that finger calibrated, bro.
It’s designed like an “escape room.” You’re not supposed to solve the riddles in a few minutes. So… $1300 for, what, a few hundred hours cumulatively of entertainment? Makes it starting to sound reasonable.
Lovely!
Fascinating as always! What are Master Ken's qualifications? I assume he's got some kind of electrical engineering background.
Great job. Greetings from Karachi, Pakistan.
As someone who watches Shango's videos, I expected those early silicon epoxy dome transistors to fail
They sure are known for that!
I expect we’ll see this one often
Better than eevblog's new breadboard 😁
Bravo!
Is the breadboard itself okay?
Looks like it. Every position I tried is OK so far.
I experienced hair loss during this repair.
Me too, as you can see!
It's fixed now.
If you will sell it for the calculated price, you can buy a used broken luxury car, fix it, sell it and buy a SMALL HOUSE.😅
👍👍
Another great restoration and a good inspiration to build a similar unit. Does anyone knows were to find those female, panel mounted, jumper wire connectors?? Already looked around, but could not find anything similar, just the regular wire mounted ones, which could work, but I bet not for a long time.
Great Tool, never seen it before - now I want to have one.

Would be great if you make a Storage Tour Video :-)

Lots of upfront work, but an unsorted and non inventoried collection of parts is as if you had no parts at all. I research each component, put in its own little bin with a label that includes all the important parameters. But then all I need to do, is go to the PNP section, and scan for a 60V 250MHz 500 mW or thereabouts, and voila!
Now the question, do all the breadboard holes connect? :)
