Yeah I got tired of always waiting on parts so I decided to spend alot of money and stock thousands of parts. As many of these as I repair a week it was in my best intrest.

On an average I repair about 20 amps a week mostly Rockford, now that work has slowed down for the winter months I will have more time for repairs.

It has been a profitable hobby. Lets keep in touch on this post I am sure we will have alot of the same issues with our basket cases.

Amp is prepped and ready for new parts.

Here is my list so far.

Protection led light, remote lead, subsonic filter switch, phase switch, rca jacks, 6 power supply capacitors, 8 power supply fets, 8 power supply gate resistors, 2 pnp and 2 npn driver transistors, 6 output fets, 6 output fet gate resistors, 1 MIC4420CT low side mosfet driver, 1 Optocoupler, 1 Op-amp, and we will start with that.

I will get everything replaced and fire up the amp and view the drive circuit and output through the scope.

OK

Replaced 6 power supply caps, 2 pnp and 2 npn drivers for power supply, replaced 8 power supply fets, 8 gate resistors for the power supply fets, remote lead, protection led light, phase switch, subsonic switch, RCA jacks and that is it so far.

I powered up the amp and NOTHING!!! No lights no NOTHING!!!

I cant think of anything I missed, something must be wrong with the turn on circuit??

I am getting voltage at the LM339 just not sure where to look??

What did I miss??

I would have to say defective wouldnt you?

seankane · 23rd December 2011, 04:10 AM

Pins 13 and 16 are the output and I see next to no voltage from them so is it safe toassume it is defective?
