Help with Pioneer SX-780

Sansui Louie

Picked up a nice one at a thrift yesterday, $10... no output.

Anyone have experience with replacing outputs and finding parts for this model?
 
Was that the one at St. Vinnies? That one didn't relay-click...likely needs new STK packs. www.electronix.com has 'em for less than $6 for the STK-0050. That's where I got my last set.

LMK if you need any scans, I have the service manual. Got a couple parts carcasses, too. Also resolder the solder points under the 3 regulator transistors, they're the ones on the main PCB with U-shaped aluminum heatsinks. I did notice the Source light took longer than normal to illuminate and was slightly dimmer than it should be, the regulator cold-solder problem can cause this. Woke my first 780 right up when I did that.

I almost bought that one....glad one of "us" got it. :)
