1936 Philco model 84 cathedral

Hi Y'all, I'm a newbie to this forum! I am repairing/restoring a 1936 cathedral for my uncle, and it comes on but just hums. Is there anything I should know besides replacing the 8uF & 4uF power filter capacitor just to get any stations?

Do the RF coils need to be pulled and/or checked before I can receive any stations? It had a bad 77 tube (burned out heater) which is on order.

If this helps you sort it out just remember 10,000 mmfd or pf = .01 mfd. So 5,000mmfd = .005 mfd.Radioroslyn — 04:23 PM
