we're getting closer, but still not completely there ; ) anyway, i'm surprised by reactions, i very rarely see anyone using this tube.
Hi
It makes a very nice CF due to the high gm and connected as tetrode. Add a CCS unden tube to control the current. It can drive a power tube into A2.
Best regards

This tube is reportedly similar to the 6E5P, so does the 6E5P also have this mysterious gold wire?
Hi Andreas,
Do you know the difference between 6Э6П-E and 6Э6П-DP? What is E and DP means?
Thank you in advance.

"В" The lamp is high mechanical strength and reliability
"Е" increased longevity of the lamp (5,000 hours or more)
"Д" Lamp particularly high durability (10,000 hours or more)
"И" The lamp is designed for pulsed operation
"К" Lamp high mechanical strength and reliability with enhanced vibration resistance
"Р" increased radiation resistance
With the wire connecting by contact with the internal glass coating, any positive voltage there would attract electron bombardment. Likely slowly vaporizing the coating and contaminating the micas and internal tube element surfaces.
Sorry to resurrect an old thread, but it is directly relevant to my question in regard to using the 6E6P-DR and proper connection of the screen on pin 8.
I have a NOS DAC design in prototype with a common cathode output stage in which the tubes are battery biased. Yesterday I made some changes to use 6E6P-DR in place of 12B4A. So far I have had no issues with both the cathode and pin 8 at ground potential. Anyone anticipate this would become a problem over time?

I assume that this means cathode tied to gnd and control grid fix biased by a battery.
So you do have a negative voltage available which you can connect to pin 8, namely the battery' s negative pole ... no current to be expected from pin 8 either.

Thanks, I'll give that a go. Considered even adding a second battery specifically for pin 8, wouldn't be much trouble.
Here is the gain stage in question.

Tying pin 8 to the battery negative terminal seems to work well, Sorento, just for my sanity I checked current draw, as expected it is 0. Thanks!
