Getting somewhere now!
I've located the proper alignment instructions for the radio. Following the instructions, I've been able to hear the tone while connected to the control grid of the 6A7. Was able to max the tone on trimmers 1, 2 and 3. Was also able to adjust the Wave Trap to min. Connection made thru a 220pf cap to the generator.
Now the trouble starts. Signal Generator set at 1400kc, dial at 140, broadcast band, still connected to the antenna. No tone while tuning the HF Oscillator.
Back to the schematics.....any clues?
