- Greetings, Getting deeper into amplifier theory--thanks Rich! Still playing with the idea of full QSK for the SB-200. I ran across a circuit in the Hints and Kinks column in the April 82 QST. The cir

- Would the SBA-2001-1 QSK board manufactured by Heath for their SB-1000 work with the early SB-2xx series? (it was factory assembled and I think also used by Ameritron) The one I have was modified wit

- Rich, Okay--what about using the relay to handle the triggering of the cathodes? Would this decrease the rough audio caused by RF switching? 73 de Tom -- -- FAQ on WWW: http://www.contesting.com/ampf

- Yes. However, with the high speed switching circuit's ECBS, whenever current flows through the relay coils, current flows through the opto input. This turns on Q1 which connects the cathodes to the
