So I bought a little sansui au555a a while back and ever since I bought it the phono section has had a strange issue where it sounds like interference coming from the right channel, there seems to be no bass at all from the right channel and the occasional popping sound from the speaker.
I recently replaced all electrolytic capacitors throughout the amp with Nichicon units including the small phono board and replaced the 4 little 2sc1312 transistors with ksc1845’s however the problem still persists so I am stumped??
It does this on both phono 1 and 2 and I have tried 2 different turntables aswell with the same results.
The amp works exactly as it should and sounds fantastic on all other sources so I assume the problem lies somewhere within the little phono board?
Any advice or ideas would be much appreciated...
Cheers..
