Zen I/V - First Watt
... The input impedance is the inverse of the transconductance of the two Jfets in parallel, which at 30 mS each comes out to around 15 ohms. The output impedance is roughly the values of R3 and R4 in parallel, and for the example shown that is around 500 ohms. Here is the distortion versus output volt ...

Heathkit TX-1 - Orange County (California) Amateur Radio Club
... On CW the Apache uses a clever time-delay differential keying circuit. This circuit uses an NE2 neon lamp to allow the VFO to start and stabilize a few milliseconds prior to bias being removed from later stages; it also keeps the VFO running until after bias is restored when the key is let up. This ...
