Tuner not working on 46-420 code 121
#3

Thanks for your suggestions.

The tuner seemed to be working fine when I got the radio so I don't know what happened.

I looked at all the solder points to the tubes and nothing looks shorted anywhere.

To check the coils I would (it seems to me) have to try to get the aluminum enclosures off and that would take unsoldering everything it the way of those irritating screws on the underside of the chassis.
I don't at this point have any meters or scopes so I was hoping there were a few things to try that weren't too difficult.

If I have to I'll salvage my new caps and pull everything to completely rewire the radio but I certainly want to avoid that.

It just bothers me that when I got the radio the tuner worked and the volume was weak and now I've gone to strong clear volume and a useless tuner in the circuit.

Thank God there's beer in the fridge...
