Clarification please: The current Eimac webpage says that the socket is the *same* for both the 3cx1200a7 and 3cx1200z7 (SK-410). Several posts said that the socket was different. Is this a web page

The bias is controlled by two zener diodes (controlled by the CW/SSB switch). Does toggling the switch make an appreciable difference in the resting current? Most likely, you have a damaged zener. It

Use a NEMA 6-20R and corresponding plug. For 20 amps, you need #12 conductors or larger. I use 3 #10 conductors with a 20 amp circuit breaker on my Centurion. The three conductors to the Centurion an

That is good to know. Given however, that the manufactures of the amps (e.g. QRO, Ten Tec, etc) don't use the larger fans (split chassis or elevated socket 130 mm tubeaxial), they derate their amps i
