As the title says, I've had a well taken care of FM-3 in the system for a few months. Thought I heard a muted "pop" when in another room the other day, and station became very noisy. I've subsequently found that the tuning range for a quiet signal is almost impossible narrow (it was not great to begin with). I figure either a tube went bad (but which one?) or more likely a capacitor went somewhere in the circuit. I don't have the schematic. Any suggestions, either DIY or via good Dynaco FM3 repair guy somewhere in New England (I'm in Western Mass).
