I acquired a Philco 90 Cathedral.
With all your help I have progressed nicely, but have now taken 2 steps back...
The unit received stations when I got it. Now it does not.
It has always had a problem with the volume control. Very scratchy and intermittent.
(Should I replaced this? Can an original be located? Can I used a modern pot?)
Since, then, this is what I have done:
Changed power cord.
Added metal shield
Cleaned all the bugs and crap out and off of it.
(I blew it off and used contact cleaner.)
Replaced the type 24 tube. (Det-Osc)
(The tube did not light up anymore.)
(The one under the 3 tube shield.)
Changed the Pilot light. (used an E10 6.3 volt)
Gee, here I thought I was doing great things for it, and now it is mad at me.
Maybe all the dirt was holding it together?
Anyway, any suggestions on where to start troubleshooting would be very appreciated.
