If... "Reactance at 1.8MHz = 3099 Ohms" Then, With 3 kv on the plates, circulating current through the choke winding and through the by pass cap is 1 amp? You see, this is a useless parameter. Circulating current is limited by parallel resonances in the winding, which present a much higher effective resistance to the tank circuit. 73, Roy K6XK
