RE: Volume Pot Question

Assuming a zero ohm source driving the pot, 25k ohms from the wiper to ground (the bottom of the pot) and that 25k ohms would be in parallel with 25k ohms from the wiper to the top of the pot (a zero ohm source).

That's 12.5k ohms WRT AC ground and thus a 12.5k ohm source impedance to drive the 201a grid....no?

Note...even if the source impedance driving the pot is 5k ohms that doesn't change the number much...25k in parallel with 30k* (*the other half (25k) of the 50k pot plus the 5k driving source) is 13.6k

BTW Sorry for the typo, I meant to type 12.5k in my original post.
