Thanks to all! Well it can't get simpler than either of these diagrams. I'll give it one more go after I buy a better pot. I'll post if successful.

New Case & Connectors
New Potentiometer
New Switch
New Input Caps
New Reservoir Cap
External Power Supply

WOW! I'm speechless. Great write-up and pics!

Audio1st, I bow in your presence! I unsoldered the + and - on my inputs from the PCB, ran them directly to a 100K dual pot (closest quick one I could get at lunch today), wiring as your diagram shows.

She fired right up!! WOOHOO!! I had a little over 100 hours of continuous run time on this amp before surgery. I'm going to connect the amp to a pair of NOS Radio Shack 4-inch fullrangers in Z-hornets (or maybe even the 6-inch fullrangers in Voight pipes) and let 'em run for a few days. I am still using a 12V wallwart (for now). Thanks again Panomaniac, PCHuggs, and BWRX as well. I certainly owe you all a round, thanks.

BTW The older models of Playstation 1 are still my favorite CDPs!

Really? What's up with them? They should be cheap to buy, yeah?

Hey Bob, do you know Tony Slafta? He's in Atlanta too and has done a few sonic amps. He loves em. You guys should get together. Contact me, I'll put you in touch.

Glad to hear you got the thing up and running. Happy Turkey Day!

The SCPH 1001 is the best model I've tried so far. Great audio output for a CDP and dirt cheap. This model and the 1002 have separate left and right RCA outputs. Clear, crisp, and detailed. There are other models to try as well, but this early model is most sought after. My last one cost more in shipping ($8) than the unit ($7) on that infamous auction site. Try it, you'll like it for the cost. Only drawback is having to use the game controller for changing tracks. The 1001 is pushing a nice signal to the Z-horns as I type, pretty loud for 4-inchers.

Tony? Don't know him but I would like to meet him since he's local. You can reach me at cruisaire@hotmail.com.

Gobble, gobble.....have a great day and don't eat too much.
