I have three of these radios. They share the same problem: No FM reception.
I have:
1. Replaced all ceramic and electrolytic capacitors
2. Swapped out tubes
3. Cleaned all switch contacts
4. Checked or repaced all resistors
5. Replaced selenium rectifiers with diodes.
AM reception is excellent. No FM at all.
Ideas?
Thanks!
