Need help!
On this CT-2 Chrysler deluxe radio, I have replaced the caps and checked all the tubes.
As stated in an earlier post I had to remove a few shorted plates in the tuning capacitor.
I cannot get the Oscillator to run. I can inject a 260 KC modulated signal into the IF and get tone out to the speaker with plenty of volume control.
Checked all the coils and all appear to be good. Checked R11 & C12 in the oscillator circuit and both are in spec. I have replaced the 77 tube twice. Both check good.
I have replaced C34 (30-4231) .25uf, .25uf. The original is a large square can with can screwed to the chassis. I did not use electrolytic’s although it looks like a duel can. Is this an electrolytic at .25uf?
Is the schematic incorrect? If it’s and electrolytic should the (-) side go to the chassis? Is this even my problem?
I have not touched the padder caps yet>
Any help or input would be greatly appreciated.
