Thanks!!

Did you add the link under the PCB when you used a single transformer?

Hi Greg,

See the attached picture of how I connected to the 2nd AC connector with one transformer. I didn't have any other connection under the PCB.

Thanks!!

The second bridge rectifier(in digital sec.)is not needed,simply adding a jumper at the alotted space on the bottom of PC Board will feed the positive DC voltage to the digital section.

Totally understood, I could run a wire from the +ve DC of the 1st bridge which is probably what Greg meant either.

It was more like the stubborn side of me trying to figure out why the configuration flowing around, as posted by Erin, would work for others but not me

Thanks,

My diagram was incorrect. Oops, sorry. Embarrassing. Perhaps the moderators could remove the original diagram so others don't make that mistake.

It didn't work for me that way as you can see that's what I did at first.
If you follow the schematic, this wiring will effective connect the ground to one side of the AC input of the +3.3 connector.

Thanks,

Yes. I see the problem now.

Just in case there is still confusion to the link I was referring to, here is a picture, link in red.

And yes, only wire to 15-0-15 terminals.

That's what I ended up doing after I saw yours and F1's reply.
Thanks for the hint!! Now, its time to make LPF correction and
other mods. Yes, I have ordered the parts :-)

For the fun i try this output stage .

There is no output capacitor because there is one on my WA6 input ( Headphone tube amp ) .

My conclusions today .
Better than the OP ,better than the direct output ( Just a serial capa ,or the RC filter ) ...
