Am in the final redoo of a 38-7, (still need a range 1 ant. coil).Have listed in wanteds. Question here is How do you change the cone presets?
I assume they loosten by unscrewing somehow and then tightning? I have tried using a screwdriver on the large slot in the tuning knob while pressing in on it while engaged on a cone but nothing catches to do anything. Is that how you supposed to do it?
Also the muting wire was removed so I re-connected it and got a lot of noisey static when tuning. Was that a weak spot and previous repairman removed it?
This set also had a tuning capacitor problem I've never encountered.
The osc. section on the lower 1/3d of the travel the rotor plates shorted out on the mounting of the stator. about half of the rotor plates touched and I ended up reducing the rotor slightly with a dremmel sander. I'ts ok now, just never had that problem before.
Anyway need advice on the cone adjustments. Also how to remove the fine tuning knob to replace whatever was there for friction.
