ADC Sound Shaper Two Voltage Output Or Service Manual

Hello everyone.

I am looking for the power output readings of the Sound Shaper Two. Not the MKII. I can find no information or crossreference on this transformer.This is a P-100686 with a 3 wire output. 1 black, 1 brown and 1 grey. I also can't locate a service manual This would solve all of my problems and the owners manual only gives the drawing with no voltages. Any help would be GREATLY appreciated.

Hi
Looks like this company was prolific at making different models with the same number LOL
I am also looking for a manual on my specific model.
Ths model I have it configured like this
The transformer in this model
Orange / 49.5V tap
Blue / Center
Orange / 49.5V
Red / 10.6V
Black / center tap
Red / 10.6V

The only manual I was able to find has one transformer with center tap
( no color information) but it's 48V cebter tap, so it would be : 24V -Center tap- 24V

If anyone has a manual for the model I have , I would really appreciate it .
Thanks,
 
Ok I have this schematic this one most resembles mine but has no voltages. Also this version, my version has a meter not the light bars. Your schematic is for the Sound Shaper two IC. If your version has just Sound Shaper Two on the front I would guess you have the same one I have. Let me know. Thank you Mike

The base circuit looks pretty close , besides the op amp section dealing with the LED display. The power supply section looks more like what I have , Besides the fact it's got 2 different voltage input from the transformer , one with full wave and the other half wave..
My front panel is marked Sound Shaper 2 mark II. Every schematic I found don’t match LOL

You don't happen to have a higher resolution version of that do you? The bottom half of the image where all the bandpass inductors and caps are located is too blurry. I just received one of these to clean up and I think it's gonna be a part donor - one of the inductors is broken off and wedged in the bottom.

I need to find some better speakers for the bench, but it sounds like all 3 of the lowest bands on the right channel do nothing and I want to confirm which bands that inductor affects.

headphones will be your best bet. that's what i use when testing eqs
 
Thanks for the response and tip! I'll take another listen with headphones in the next couple days.
Right 30, 50 and 90 don't seem to change the sound or meter at all - the Left bottom 3 do make a difference. So, will have to check for other cracks or broken connections in that area of the board.

Much appreciated!
