Thank you Morzh,

The model 80 I am working on had been kinda sorta "restored" years ago by someone.
I had read somewhere that the tunner assy was mounted on rubber bushings, so that's why I am asking if it is supposed to be shorted to the chassis or isolated?


The volume control has been replaced, I see a cardboard sheet sandwiched between it and the chassis, the front side has a washer and nut securing the pot to the chassis.
I had read somewhere about a  "fiber" washer on the potentiometer, so I  was wondering if it too should be isolated from the chassis?

Thanks for your help.

After doing the alignment, and per John Riders instructions on aligning Philco radios, I am only receiving on station, with a fair bit of noise. 
So was wondering if these may be affecting reception. 

I live south of Reno near Carson City, there are 10 AM stations in the area, but I can only pull in the one in Carson City which is nearby.

Thanks for your help.
Lewis
