Default Power Acoustik 5500/1

I picked this amp up locally for cheap in the hopes i could fix it. Ive powered it up, light comes on, but no sound. Im getting 13.8 volts at the B+ and remote terminals. Not sure if this matters or if its normal for the amp but when it powers up and sutss off theres a clicking sound. Looking inside it appears to have no damage, whats the first place to look or test? Thanks

The BAMF 5500/1D has relays which click. Is that the model you have?

Negative. I saw one the other day at a pawn shop, its a BK Precision for $60. Not sure i wanna buy one from a pawn shop though. Are scopes the best way to check them? Thanks


I actually found the same one on ebay,

Most pawn shops offer a 30 day warranty.

A scope makes it easier to check a lot of things.

Do the relays look melted? They often melt on the area shown in the attached image when the contacts fail.

If you're going to try to get that scope, let's wait until you get it to do anything else.

Have you made sure that all of the small boards are fully seated on their connectors?
