Not sure if it will. The 37-33 requires two bias voltages  -3 and -9v. It's simple enough to wire up a battery or two for these voltages. Then all you need is +135v, 90v, and 2v for the filaments. Be sure to throttle back the filament voltage if you have been using the p/s on a set with 01A's.

ps After looking at the link it should work fine!!!

Thanks!  I had already ordered it.  I know I could rig it but I am getting lazy in my old age.
