Man I have been racking my brain trying to get these voltages and resistances in line. I found one bad resistor and a couple I used an incorrect one. I also found  I used an incorrect cap mf on one location and also was missing a resistor. Long story short, I guess after changing so many components my brain started farting. Anyway, the good news is I am making progress. I got the two 6V6 pin 2 voltages corrected and the 6BA6 pins 6 & 7 voltages corrected. The only ones I am having a time with is the 7F8 and the 7R7 and after checking everything I am at a loss.
I made a little bit of progress on 7F8 pin 3 I got it from 289V.DC to 228V.DC and on pin 6 it went from 240V.DC to 222V.DC. they should be 103V.Dc & 165V.DC respectively. Also both test open in resistance to ground and I see no reason for it. They should both be 190K. Pin 1 is still 0 and not -6.6 and pin 8 is 0 instead of -1.5.
On 7R7 pin 4 has 33V.DC and should be 3V.DC. Pin 5 is 220V.DC and is supposed to be 92V.DC. It also tests open on resistance to ground. Pin 7 is 45V.DC and should be 1.1V.DC. Other than that all other voltages are within tolerance.
Any ideas or help would be greatly appreciated. Icon_confused
