I had to look up a pdf on the 8AP4 to understand what you meant, I see now where a 10BP4 has G2 on pin 10 the 8AP4 has no connection on pin 10, I was assuming it used the same gun
It shows G2 as being connected to the 2nd anode, which would be the shell of the tube in this case.
I don't know what to tell you at this point, perhaps just try and test it omitting the G2 adjustment and see if that works, or maybe you could connect the anode to pin 10?
