content: I'm obsessed with these things. I love the design and build quality. I picked up 2 yesterday at a local hamfest. I snagged a 5015A and a 1010T. The 5015A works well. The case looks like bloody hell so I pulled the cover to spruce it up a bit. That's when I noticed 2 caps that had warts lol. I can't decipher the values and was hoping someone had a manual or schematic? I will upload a picture when I get back to the lab. Any help is appreciated.Robb

content: Those caps are sleeved, I find foam cleaner works a treat and you can then read the values.David

content: Spot on. A toothbrush and some IPA. Excellent advice. Thanks. I have added 3 pictures. They are both Sprague. Both electrolytic. I can’t decipher the values though. Anyone?Robb

content: I’m reading 25.54uF @ .24ohms and 1638uF @ 0.08ohms. Thoughts? To me they drifted up but the ESR is fine.

content: Remember old capacitors have a much wider tolerance than modern ones, usually something like -20%, +50% or even +100%.These days they have the processes perfected, to produce them nearer the bottom end of -10% tolerance, to minimise materials used & maximise profits.Also note measurements on old stuff, should be taken after they have had a chance to reform and heat from soldering can temporarily affect the readings obtained.David

I wonder why they don't come up for sale often

content: I’m up to 4 now. My wife is going to divorce me soon. One of the 2 I just bought doesn’t work at all. Should be fun to fix. It’s a 1010T if anyone has that manual or schematic?

content: Thank you. I was able to get the manual from a previous response but both of these manual downloads only contain 7 pages. I suspect whatever is missing is what’s needed to adjust the unit. I appreciate your help and feedback.

content: Does it actually need adjustment?As others can now find the manual/circuit, the rest can be worked out.The panel meter is adjusted with R22, the others might set the maximum current (R31) and maximum voltage (R19) available, maybe others can confirm?If it's out of adjustment & no-one else replies and you want to find out yourself, mark the settings of the adjustors (so you can return them to the previous position), move them a little & you should figure it out.David
