And that's with all new B+ filter caps?

Because that's still a little low.

Just put in new 5u4 E H tube
Voltages reciter pin 8 397 vdc

v6 pin4=396vdc pin3=362
V5 pin4=363vdc pin3=365
Bias v5 -30.4 v6 -30.5

Amp sounds pretty good to me

What do you think?

Your pin 4 measurements should be identical.  Pin 3 can vary a few volts from each other, but not the screen, and definitely not a 33v difference tube to tube. Recheck your voltages.

I missed that on the pin 4.

Yes, recheck ALL your voltages. Do this with ALL tubes in.

Rectifier tube, pin's 4 and 6 acv and pin's 2 and 8 dcv. Then the 6V6 tubes,

dcv- pins 3, plate
dcv- pins 4, screen.
