Using two transformers in place of one

[jordheis]

I think it's an ADC (versus ADS)

This is what I have for readings

All we need is the reading on ohms for:

Shorted together probe tips resistance
primary winding resistance
secondary: center tap to one end resistance
secondary: center tap to the other end resistance

Mike,
It is a very important starting point as stated above is to short those meter leads together and show reading. It is very unlikely that all are showing 0 ohms, so that is why we need to verify this first. Thanks for your patience here.

Found the power supply schematic for the ADC SS3 which uses two separate secondary windings, one for 60VDC and the other for +/- 26VDC, I don't see why two transformers can't be used to do the job.

@mike5555
Can you post the schematics of ADC SS2 MK I?

 

[jordheis]

I posted it in the thread a bit ago for all to review

Thanks @jordheis
But I can't find the T301, bridge rectifier D221 and C213, C214, D219, D220 and C209 on the schematic in post #21.

Try this from Hi-Fi Engine.

Sorry. File is too big for me to post. I found what we need at Hi-Fi Engine. Search ADC SS2 MK 1. SERVICE MANUAL and more, BUT be sure that you are getting exactly the model that is being discussed. This is causing some confusion. Not just with ADS/ADC but also which exact model it is. The models did vary circuitry.

@Ixnay
Can you post a screenshot of the power supply section? I never got my Hi-Fi Engine download to work!
Thanks

Sound Shaper Two

Sorry. I am having a Hell of a time even getting this far. Not very computer savvy.

Well, we are all linking to the same page "Sound Shaper Two" at Hifi Engine. I've downloaded both service manuals and neither of them listed at that location have the same paragraph the OP posted so maybe the manual we need isn't up there....
@Mark5555 I suggest it'd be helpful to get a pic of the serial plate and front panel.
