Thank you, Brandon!

Nice use of these old blue caps from these SF Fender amps. These caps always sound awesome to me. 8)

I'm pretty sure this is the power supply:

Fantastic work on the PS, that is it from what I can see-

The only other really important thing to note is the send control is 10K

Thanks!

Do you mean that the Drive control is 10K?

Is there any way to make out the choke part # under that tar $#@%?

You have the grid resistors switched with the grid to ground. 220K is the grid and 270k to ground.

Standard 20M feedback but with .1 on the caps, both plate and feedback loop.

47uf bypass cap.

100K plate load.

The cathode follower side should have a 1uf on the cap to the send pot. The two trides are paralleled.

Hope this helps!

The choke is a triad part no longer made, but it's 10H 500 ohms 50 mA.

Here's the updated one. See anything weird?

Is the Dlator II using 12AX7s?

Are you sure about where each power supply node goes? Seems weird to me.
