I got a couple cheap small amps, Phoenix Gold Ryval v1502 left channel is dead thowing out DC voltage, And I got a Soundstream USA100, The amp works but when adjusting the gain pot the left and right channel will cut out and now I think its the left channel that will not come back pretty sure its the gain control causing this issue.
I'll see how these pan out if you take on the job, Then I got some other amplifiers that are up on the spendy to purchase list that need some work.
