Q:DN2540 CCS protection diodes




I had built some DN2540 CCS plate loads a while ago and used them without protection diodes.

I'd like to add some circuit protection before trying them out again.

Built a simple 6SN7 preamp circuit with back to back zeners from gate to source in LTSpice4 and it ran OK.

All I have are 5.1V zeners, so I used a string of them.

If I can find a 15V - 18V zener at Rat Shack, that might be easier implement.

Let me know if this is good enough or not.
