I'm covering that scenario. I also did not see anything that looked like a burned up capacitor.
It tested on the low end of good, but not weak or bad. There is some rust on main transformer but I doubt that is anything more than cosmetic. Here is a super clean example of a Heathkit aa 151 integrated tube amplifier. I have an Eco tube tester, so I tested all the tubes while I was having a look.
This is the perfect piece for someone who has some technical skill to fix it, or is willing to spend a little to have it repaired. I am not an electronics technician.
Please look closely at the photos and ask any questions. I looked for obvious signs of malfunction when I opened it up to take these photos but could not see any. The shipping price is for coast to coast. I can only imagine that whatever is wrong with it is probably a very simple fix.
I know the four power tubes don't look great in these photos but they all tested very strong. They all tested very strong except for the rectifier. Obviously sold as is.
