Thanks Allen!
Yes, I thought to use 1K for grid stopper, but a saw many design without it and it confused me.
What about the output bleeder resistor? 1M or 470K? I saw even 10K.
Tyimo
bleeder resistor is there just to discharge output cap , in situations where same is "loadless" .
lower in value - faster discharge..... nothing more
feel free to use anything form 100K , up to 1M
Tyimo,
I would start with a 1k grid stopper - RIGHT at the grid pin on the tube socket - and when it's all working maybe you could try reducing it down to say 330 ohms, but I wouldn't trust anything less than that. Unless you have 250MHz scope/or spectrum analyser and know how to use it.
What ZenMod says about the bleedeer R is correct, I always use 1 meg. 10k would be just stupid, IMO.
