Per Sams have you tried injecting your test signal direct to the mixer grid? With the oscillator tube removed and signal connected to the mixer grid there should be no reliance on channel selection, because the mixer is post any channel tuning. You could also inject the signal to the shield of the mixer, keeping the shield insulated from contacting the chassis.
