[Amps] Quad Tube 4cx800 hf amp

[Peter Voelpel]

In the Harris manual of the RF110-A the driver tubes are shown as 8122 and
the 8660 finals as 4CX1500B.
Agreed on the tank circuit.

Sorry for the error; 8660 is the Harris designator for the 8122.

Also, the tank circuit should be designed for a Q of 10-12 at the voltage
and current drawn at 1.5 kw, not 20 kw.
