sta2100 up in smoke

Sorry, no I do not. I am a native conch though now living in SWFL so I figured that you would get my attempt at humor.

Yep, got it born and raised here also.

That STA-2100 is a beauty for sure. You maybe will have better luck with posting for help on the solid-state forum. I hope that you will get it sorted out

Is there a moderator here that can move this thread over to that form.

You can make that request to move the thread directly by 'reporting' your own thread. Just click the Report link at the bottom of your post.

Good luck with your STA-2100!

Ordered a new one, do you guys think by just replacing this one will work? Thanks for all in input, learning lots here, great site

That cap was the weak link in a failure, likely a dead short ahead or behind it somewhere. Gotta find the cause & remedy that first.

Try firing it up on a dbt….

How will that help, since it's already wounded?

It will help locate the wound…

Did some studying and I disconnected the power amp boards one at a time then power up the receiver. What I found was when both amp boards are disconnected the receiver power up and turns to green light. So I have something blown in both amp boards. Could I send in just the amp boards with heat sink to be repaired, if I could find someone.

The problem with that is that whoever attempts the repair won’t likely have a good way to test the driver boards. All they could do is replace parts on the boards. The boards need to be powered up and voltage needs to be measured at various locations on the board.

that's what i thought, who can i mail this to? i'm in key west and no one close that i can find. Or buy the boards and install myself

You could rebuild the boards yourself, if proper parts could be found. Start by checking all PN junction parts with a DMM or VOM. ( transistors, diodes, etc). You'll likely find output transistors shorted, perhaps a diode or 2 also.
If you're comfortable pulling the boards, you should be capable of this. Be sure to take pictures prior to removing anything !
