B&K RF Signal Generator Repair
#34

Probably not.

But if you put a small 12V zener from Q3 collector to GND (remember the Zener goes "-" to Collector and "+" to GND) it will protect it, clamping positive surges to 12V and negative to 0.7V.

Make sure the zener has low parasitic capacitance.

Or you can do a clamp from the Q3 collector with two diodes, one to 9V and another to GND.

PS. Oh, you should use a small capacitor from the generator to your radio ANYWAY, ALWAYS.
