Correct amoundo!
Let's take a journey back in time abt 4hrs ago.

>>This is fine if there is something else connect to pin 6 also as it has no internal connect to the tube. A common configuration would be to have the 220 ohm resistor between pins 8 and 6. 6 being used as a tie point also it would have the 1200 ohm resistor connected there.<<

So are you saying that there is no terminal on the tube socket for pin 6??? I realize that there isn't a pin on the tube base.
When my pals were reading comic books
I was down in the basement in my dad's

Vol 1-50 admiring the old set and trying to

Circa 1966
Now I think I've got!
