Power Acoustik 5500/1

[radwilsons5803]

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?

 

[radwilsons5803]

Yeah, forgot the D on the end, i apologize. So what do i check first and thanks again

 

[Perry Babin]

Do you have a scope?

 

[radwilsons5803]

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,

B&K Precision 30MHZ Dual Trace Oscilloscope | 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.

Ill throw an offer at them this weekend and see what comes of it. The two relays look good in this amp. Anything else i should look at? Thanks

 

[Perry Babin]

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?

 

[radwilsons5803]

I have not, ill do that right now! If not ill get back to you when ive gotten the scope, thank you

 

[radwilsons5803]

They are fully seated and still no output. Hopefullly getting the scope tomorrow or monday, thanks
