Dear administrators

The pinout presented on PL841 is wrong,the G2 is connected to pin1 not pin 9. Has can be seen in the circuit diagram (left side) G2 is connected to pin 1. I also have this tube, when i was testing it,i had almost no emission, until i found a pinout diagram that presented G2 connected to pin 1. When i connected the G2 voltage to pin 1, "voila" normal emission. When looking inside the tube pin 9 has no connection. So the pinout is diferent from EL84, unless, there are variants on this tube with diferent pinouts?

Kind Regards,

Aires Gomes

Thank you, Mr. Gomes!

I made a new drawing with the correct connection of g2. Will be uploaded soon...

By the way, Mr. B. Mak made already the same suggestion in 2015.

Regards.
