Nietzsche NB-30 2m "linear" amplifier

Yea sure, the front panel says "Linear Amplifier". No such luck. It's class C.

The power transistor is a 2SC1946A, but not this one (wrong package -- it's not a 4L FLG) and not this one ( wrong pinout -- 3 is the base and 2 and 4 are the emitter) but this one.

Correct 2SC1946A pinout

The 2SC1946A is a 30W device with a gain of 10dB, which is remarkably high compared to the 2N608x devices I'm more familiar with.

I might be able to use Harry's biasing to convert this thing to a true linear but it's more of a hassle than it's worth I suspect.
