>So do you mean,V3 tube pin3 cathode, and pin 5 plate, need 100uf to Ground on each?

No. V3 has a cathode resistor; where that resistor goes to the power supply should be at least 100uf that is bypass for the power supply. In older amplifiers the cathode resistors of both V3 and V4 tied to the same point.

>On v4 I have always had 330uf on the plates I did not have 100uf.

Good.

>>In the production amplifiers there is a separate leg in the power supply for the cathode circuit as well- that also has a minimum of 200uf.

>Are they 100ufs in front of the 45kohms pin 3an pin6 of V4 to ground?
>thanks

If you have 330uf bypassing the plates of V4 I'd have 330uf to bypass the power supply connection of the V4 cathode resistors as well.
