There are some high voltage RF fets on the market now that have low input capacitance and high gain at 30 Mc that are reasonably priced. This allows for an amp with no transformer in the supply to run from 120V mains and a simple rectifier and cap for the supply. The problem with solid state devices is designing the protection cct. to save the fets from mistakes. 73 Steve _______________________________________________ Amps mailing list Amps@contesting.com http://lists.contesting.com/mailman/listinfo/amps |
