Philco 46-480 Electronic Restoration

The sleeving for the transformer arrived early, so I went ahead and finished reassembling. The chassis looks far better than I expected! I’m very pleased with the outcome.

   

   

I plugged it in using an isolation transformer and powered it on. All of the tubes on the main chassis lit up, but the two on the RF chassis did not. The first in line on the RF chassis to receive power is the 7H7 used for the 1st IF transformer. I tested pins 1 and 8, and I believe there must be a miswire somewhere. My multimeter alternates between seeing 6.3V and OL when measuring AC voltage. Looks like I’ll have some hunting to do. But I am excited to see the chassis powering on and the dial lamps illuminated. That’s probably the first time in decades that this radio has had any power flow through it.
