[Amps] DC Blocking Capacitor

[R@contesting.com]

The value of the DC blocking cap is seeming less critical than is 
commonly thought.  As I understand it, in most HF amplifiers, 200pF is 
enough.  However, the I-handling ability become important on the 28MHz 
band since most of the tank circulating-current passes through the DC 
blocker on its way to and from the anode..
