Sold ADS PQ20 4 channel amp

[Mr Bojangles 10+ year member]

This amp still looks decent as you can see from the pics. The only thing wrong with this amp is the 2nd channel has a scratchy sound that has been intermitting for a little while now.. Other than that the other 3 channels sound great. I just don't have time to mess with it.. i'm letting it go for $60 plus shipping.

any idea whats wrong with #3?

i could use this, but dont want to deal with it if i have to repair it.

 

[Mr Bojangles 10+ year member]

not real sure.. I've heard the mainboard might just need cleaning or dusting.. I feel like it's something minor beacause the scratching comes and goes..

does the sound still persist if you bridge them?

Bump for a kick *** old school SQ amp!

The only challenge I had with my old PQ20 was the multiple runs of 10 gauge for power and ground.

Yes it does.. But as long as there is nothing wired to the scratchy channel it sounds great.. So i guess by bridging the scratchy channel (1) with the clean channel (2), you get 100w on the 2nd channel if you wire the speakers up to channel 2.

Yea.. I just split the wire and went into both holes of the amp..
