Philco 60 Alive Again!
#1

Hello Folks,

Pure amateur here, and my first old radio, so bear with me.

I'm working on a Philco 60 that I acquired, that has not worked in over 40 years. The previous owner had "worked" on it and made several schematic wiring errors, including two dead shorts, not to mention poorly chosen component values. It's a 1935, so I'm working from the December 1st 1934 schematic. I've since recapped the radio, and painstakingly matched the wiring to the schematic. Went through the proper procedures of using a variac and dim bulb tester. Low and behold, she powers up. Volume is working properly as is the tone control. Other than a couple of foreign stations, on either setting of the band switch, I am not getting local broadcasts.

This is where I can use a little help. One thing I noticed that the previous owner had done, was to run a ground wire from the chassis to the frame of the tuning capacitor. It looked home brew to me so I left that wire off. However, after first turning on the radio, I received absolutely nothing until I added a test lead, and once again grounded the capacitor. Should this be grounded? I have installed new rubber grommets under the capacitor, and it is clearly isolated from the chassis.

I had purchased a NOS and tested 6A7 tube, so I'm starting to think that one of the coil windings on the antenna coil may have an open. Correct assumption?

I don't have a way to test the 78 and 75 tubes just yet, but since I'm receiving foreign stations, I'm targeting that coil. Make sense to anyone?

Thanks much,

-Brett
