We used another radio to listen for the oscillator on the Majestic. The oscillator worked throughout the entire band so that is not the culprit. I would guess something with the detector section. Maybe the detector section of the tuning cap is shorting out at the upper end of the band.
I am still looking for the volume pot from the parted out set. I think that the set I parted out was a model 300 since I remember it having a saturable core reactor in it. However, according to the schematic the volume control has the same value as that in the model 310, 200k ohms. I was able to find what I think was the tone pot from that set with the power switch on the back. Have you tried spraying some contact cleaner inside the volume pot? If the pot is constructed the way that many pots were from that era, it may be repairable. I will have to take this tone pot apart to see how it is made.

the piece of carbon that goes around the inside of the pot is worn beyond repair. I've diassemebled the entire pot and done a TON of messing around with it on a multimeter and nothing helps. This pot is much different than any other I have seen, I think it is poorly designed.
Mine has the tone control which seems to work OK. the tone control is rated different from the volume one IIRC so I don't think it would work in the volume cntrl spot. But if you don't need the tone control I wouldnt mind having it as a spare. Henry |
