Yes, I'll keep the thread posted. Status right now is "bouncing around in Memphis".
I'm guessing this isn't great... (Attachment Link) Nope, not great at all... (Attachment Link)
Did somebody leave the childproof cap off the Dragon's happy juice?
Follow up plans: The cleaning and removal of stickers is done. Both top and bottom panels are going to get painted. Get rid of that faded beige.The power supply will be re-capped. Once that's done and the verified investigate some minor issues noted on the 100VDC and 1000VDC ranges.

Not sure about the large cap in the power supply section but it does seem to be blown slightly to me in the photo.

I don't think that you're going to have much of a problem with contact issues on those cards as they are similar if not the same as those used on PC's. Not sure about the large cap in the power supply section but it does seem to be blown slightly to me in the photo. IIRC you will need to withdraw all the cards in order to gain access to power supply section in order to recap it anyway.When those panels emerge from the painting process, will they be blue by any chance?

That LM323 is a 5V linear reg iirc, has it failed short and assassinated the transformer? [/color][/b]
And, no, don't let him get that pole up. Have you lot forgotten what happened last time?

Will probably run another day to verify the volume ...Cold symptoms. Headache, cough. Even though I have been in pretty strong self isolation. No fever though.rats.Lets hope that all you have is a common cold

Quote from: Neomys Sapiens on March 25, 2020, 03:51:03 amMy experiences were similar, but more costly, as I fell to the hype of it's big brother, the LM338. I got my fingers on it aged 15, wayyy before I understood thermal design. Whoa! 5A from 1.5 to 37V, and protected against everything. And in an early bout of entrepreneurship, I even sold one such unbuilt PS to my chemistry teacher. Those things cost about 30.- DM at that time. Oh my, that got ugly fast. They cooked off before I could even touch a control. Days of shame...Then, much later, I understood what happened. I called myself a fool and thought that I am done with that topic. Until the Internet came. And with it, the incredulous tales of people which were doing exactly the same thing all over again.That's just the way "real" engineers learned their profession. Nothing to compare with today's youth, just copying some shit from the internet (OK, I had a book), not knowing what they do (OK, we didn't either) and then complaining on the internet (Hmm, we couldn't for some reason I can't remember ). So we had to understand the stuff to be successful, while today they blame the supplier ...
