You could always put a variac on the HP-23 and use a separate transformer for the filaments.  That way no mods and no wasted power either.

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,

Russ Tine K1RWT
