Glad to see you here Dave! Did you ever get that Philco and RCA 17-T-150 going? I never looked at either set except to peek inside.

RCA 17s150 & Philco 21 in. table model.
Hello Mark. Thanks for the welcome. I brought up RCA on a variac to check status of power supply. This RCA is unusual that it uses a voltage doubler and selenium rectifiers. The 17QP4 checks good so i'm going to restore it. Didn't try the philco yet. Best regards, Dave.

Welcome to VK
 A lot of early Motorola and GE sets use selenium doublers too. Easy way to save cost and weight. Not so great for safety though. Bob
