Replaced power supply all is well with that.

Replaced all outputs as there were many shorted. Amp worked great.

Let the amp sit for a few months, was gonna sell it so I powered it up and it drew 20 amps current then subsided and worked fine.

I know thats not right so I let it sit overnight and powered it up this morning, drew 20 amps of current and blew every output.

I think I have an issue with the audio driver board?

Did it really blow EVERY output or just one from each group of outputs?

 

[seankane]

It blew 1 from each group on one side of the amp.

I removed them and re powered the amp and it blew the rest from that side.

I removed them and re powered the amp and blew several on the other side.

I dont know whats going on this amp worked great, played it on the bench for hours. Let it sit for awhile and now this??

If this is one that you removed before you started using chipquik, it could have an intermittent connection due to a damaged via.

No its not but it was worked on before, and looks like the driver board was removed previously, as I see some work done on it.

I guess I will take it out and check it out.
