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..
