Philco 45C restoration
#32

I've mostly completed the electronic restoration of my 45C.  It sounds surprisingly good!  And, the radio performs with very good sensitivity and selectivity.  I'm fairly impressed and I think you will be as well, morzh (at least I hope so).  My volume control is definitely a problem and I will be looking for a replacement.  The cabinet needs a bit of TLC and I will probably refinish it sometime.

My restoration used most of the old wire except for the high voltage lines.  All tubular capacitors were re-stuffed as were the electrolytics.  All dog bone resistors remain in circuit with an added hidden parallel resistor for those that were way high in value.  I avoided bending the PT wires and coated them with a couple of coats of clear "corona dope" acrylic plastic from GC electronics in the hope that it will add a tiny bit of insulation value.  I need to find a couple of tube shields.

This radio also has the 50K resistor that morzh talked about earlier in this thread.  Mine measures 35K so I added a 15K in series.  This resistor drops the voltage by only about 5 volts so I'm not sure of what its purpose is.  Perhaps to slightly increase field current???  Removing the 15K drops the voltage by another volt or so.  I may just leave it out.

Morzh, do you still need a dial cord diagram?  I could take a couple of pics.  It is quite straight forward.

Here's a few of pics:
