40-201 oscillator not working.

If the oscillator voltages are correct it should run regardless of the RF signal coming in the antenna. The oscillator signal is combined with the RF input in the mixer tube. An AVC problem shouldn't affect the oscillator. When all the oscillator parts are good then maybe the oscillator coil is wired wrong. It should be connected to provide positive feedback to sustain oscillation.
