did you have any problems tuning the volume antenna? I followed your directions and similar ones with the same results. The I adjust L3 til the gate LED comes on and the pitch comes on then back it off but it still won't control the volume. If you have any suggestions let me know please.
The L5 Choke Coil, which works to couple the oscillation from transistor Q4 to the volume antenna, might be open-circuit. The same 7v dc that's on the collector of Q4 should be out on each end of this coil, and the antenna.
