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. dt 667 |

A gate stop resistor and a 12V zener. Thanks. dt 667 |

OK, that's good to know. Alex |

They had 12V IN4742A zener diodes in stock. |
