Finished recap and tube checks. Replaced 35Z5 (open filament). Someone had been there before me and installed a couple of dual section capacitors on the power supply side which I removed along with the old wax types. Did note that C5 was missing. Replaced missing lamp.

Constant hum on power up. Also, noticed lamp get much brighter as tubes had time to warm. I added a C5 capacitor and no hum and good station reception resulted.

Planning to leave the C5, add 330 ohm across the lamp, and a polarized power cord.

I'm just getting started in restoration so comments appreciated. Thoughts on why the C5 was removed ? Anything on power cord connection point?
