[Amps] AL-80A - Won't tune on 160m.

[Bill Coleman]

I managed to fix my issues with the metering circuits on the AL-80A. However, while it appears to work correctly on 80-10m, I cannot get the output network circuit to resonate on 160m.

I hooked it up to a dummy load, fed about 35 watts, keyed and tune. Peak output is achieved at maximum C for both Plate and Load, but it’s only maybe 100 watts out, and the tuning is very broad. Nothing like 80m, which works fine.

Any suggestions?
