Quite correct Tom and I apologize. I'll be more careful with my snipping.
I did have a good look through my odds 'n' ends and I didn't find any JJ 6V6s so I can't check. I do have four matched JJ EL34's so I looked at one with Vg1=-10, Vg2=250, Vp=300 gave an Ip of 105mA. The JJ datasheet gives 135mA, an acceptable tolerance IMHO. Not that it necessarily relates to your issue, Bruce.
