Hello all,
Been reading around this forum for a while as I've recently gotten myself into a challenge, trying to fix my ITT 8033 amp. All great tips and lots of knowledge around, so I hope I can get some help with my project.
The amp's relay used to cut in an out or amp would not turn on at all so I changed all capacitors on the power supply board. I checked the output transistors and they look good, so eventually it started working, with none of the popping or hissing sounds from before.
It worked like that for a few days but since last night I have started experiencing problems with one channel - it would either cut out about 50%, meaning that I would not hear the mids properly for example and overall volume would be lower on it. If I turn the amp off and back on it may start playing properly without problems.
Issue is narrowed down to the amp because flipping the cables would cause the other speaker to exhibit these issues.
So in short, it's intermittent, it's not an all or nothing issue (only some frequencies for the most part), and it's on one channel only.
My question is, where would you suggest I start with my checks?
Thanks in advance!
T.
