I have two Sansui BA-3000 Amplifiers that have been giving me nothing but problems. They have both been not working now for the better part of a year. I have started a couple of post here in the past trying to figure out what is wrong with them but the posts always seemed to fizzle out and I have never been able to get either of these amps back to working. The one I am working on now has had all of the caps except for the large 22000 uf/80 volt replaced with high grade Panasonic and Nichicon caps from Mouser Electronics. This BA-3000 has the correct voltage on one of these large 22000 uf caps but there is no voltage on the other of these caps. When I check the B+ voltlage on the F-2512 board it is there. I do NOT have the + or _ 35 volts on the F-2512 Board. I do have the +60 volts on the F2512 board but I do NOT have the -60 volts on the F-2512 board. I have a F-2507 Power Supply board plugged in that has proven to be good but until I can get my +-35 volt issue and my issue of not having any voltage on the one 22000 uf large caps I am not even trying to plug in my F-2508 boards in. I also want to add that the F-2511 Speaker Protection board seems to be working fine as the amp does go out of speaker protection and the green light lights up. I love these BA-3000 amps when they are working and it is really bothering me that I can't seem to get either of the BA-3000 amps that I have to work. I am not an electrical engineer or anything close to that but I have been working on my own audio gear for some 40+ years. My soldering skills are great, I have good testing gear, and I pretty much understand most everything when it comes to the parts that make this amp work. I have a huge supply of components for the BA-3000 Amps but none of this so far has helped me get these BA-3000 Amps to work. I sure could use some help getting these 2 amps working again.
