I gave a 38 116 to my cousin. I have replaced all caps and out of tolerance resistors. It played well over a year.

Recently it died so I drove out to see him over the weekend.

Cheking tubes, the RF rube was dead. I also had no voltage on the plates of the first audio and oscillator (6N7 and 6A8). All components there were correct and not shorted or open where appropriate. While we wait for a new tube, would a dead RF tube cause the radio to go silent? I think so but would like an expert opinion to help with troubleshooting if that's not it.

Thanks
Steve
