Seems reasonable to have some kind of interlock for this -- a couple dollars worth of parts could easily save several hundred in new tubes. A friend of mine switched to a pair of 3CPX800s because the

I have the same experience with 4CX250B's. Sometimes the phase-sequence sensor for the 3-phase blowers in the Standard Radio CT1000's 1 kW autotune PA's failed to sense backwards rotation and the con
