JJ 6V6S Limiting Values

Post by brewdude »

I recently discovered an alternative data sheet for the JJ 6V6S and noticed that the limiting circuit resistance value for Grid No 1 in fixed bias was stated as 0.1MΩ.

First question: Does this mean that the grid stopper resistor + grid leak resistor should not exceed 100k?

Second (probably stupid) question: Does this mean 100k for each individual tube? Or, is this for a push pull pair in parallel? That is, each tube could see 200k with a net parallel value of 100k?

Third question: Should I try reducing the 220k grid leaks in my 6V6 D'lite? Perhaps I could try and tack on a parallel value to each resistor in order reach an equivalent value of under 100k?

Fourth question: Will it make a discernible difference? If so, what kind of a difference might I expect?

By the way, the listed limiting value for Grid No. 1 circuit resistance in self bias is listed as 0.5MΩ

Hmmm.... I guess these are dumber questions than I thought.
...Oh well, perhaps I can find some time this week to experiment.

100k for the grid leak, for each tube in a push pull pair, fixed bias!
