Lasonic trc920 right speaker crackling!!!

[baddboybill]

OK in an old thread I thought I needed a new speaker, well I just reversed my speakers and its not a blown speaker. So the problem is a slight crackle out of right channel especially at low volume . Any ideas would be helpful, I have already deoxit the pots...

Plug some headphones in the jack and take a listen. Do you still hear the crackling?

My guess is that either a capacitor, transistor or the amp is on the verge....

I have checked the ext, speaker and headphones output with same results but I noticed when you turn down bass you can not hear crackling
So can anyone help me to test the circuit? I know Pedro (sucess) helped me from s2g over a year ago with my helix 4636 and we got that repaired
