Hello Russ

You might consider building a power supply like this:

Diodes can be used in place of the 5U4 tube.

This site built a power supply using a Stancor P8622 isolation transformer like this one:

He did not give a schematic but it is a simple power supply.

Good luck.

Hi Folks,

I'm new to the list, and I am looking for some advice about using an HP 23 power supply for my T-22.

I still use the power supply for my HW 101, so I do not want to make any mods to the PS itself, I would rather add a voltage divider external to the PS that I could plug in for the T-22 and remove for the HP 23.

Thanks in advance and 73,
