Default Bi-directional Linear amp - news of the weird


"coffelt2" wrote

Anyway we were talking about how the linear improved the transmit signal
strength, but did nothing for the receiver and he wanted to also build a
small receiver preamp to put inside the linear cabinet, and we both got
the samw brainstorm, at the same time. Why not wire the linear up so it
would work in BOTH directions? I suppose a grounded grid preamp using
tubes with a combined plate dissipation of some 300 watts seems crazy,


Try 1000 watts for the combined plate dissipation.


and one's first though would be "you'll blow up the receiver!".


Just wait until it goes unstable and oscillates. Bye-bye receiver!
