Pioneer A-757
Hello Everyone!
I have a Pioneer a-757 amp, which is my favorite, I have it for a really long time, and never had any problems with it (it's been through quite a rough time). Unfortunately it started to take longer and longer time to start up, and now it's just won't come alive. I's turning on, the led is on, and it's getting warm as well, I took some measurement and it's quite same as on the schematics, it's just the speaker protector relays won't switch. (Once it did, when I turned the phono eq on, and it turned off when I turned it off ... strange). Does anyone can give me some advice what to look for? |
