Single Ended Triodes (SETs), the ultimate tube lovers dream.

Is there a secret to using the 7A4?

I hooked up according to the base diagram. it is taking the place of a section of 6sn7. B+ is 300. Plate resistor 80k , Cathode resistor is 360 ohms. Filament voltage is 6.4vac. I am using it as a driver tube.
I put signal on G1 and get nothing. I just did the same circuit with a 6j5 with no problems
