Dual power supply question.

[Ian444]

Does the shared primary winding negate the channel separation benefits of the two output supplies?

Depends which benefits you mean.
If you mean totally separated DC supplies, it doesn't obviously.

Thanks. Would there be any benefits at all of the above schematic vs paralleling the two secondaries and using a single bridge rectifier and C-R-C filter?
Background - I already have the Triad tranny and just wondering what power supply config to use for a PP 6P1P amp I want to build.

It looks like a voltage doubler on each output to me.

Yes, voltage doubler. 👍

No. There's no audio there.
