I took all voltage readings and measured voltage on both sides of the 220K plate resistor for 7X7 (245v, 145v).
I'm only listing what I think is suspect readings, but I do have them all and these were taken @ 117V AC. I did notice that when I clipped the test lead to pin 8 of the 7F8 I had great reception and volume.
7F8
1 = -3.1 (-4.7)
3 = 120 (110)
5 = 6.7 (8.6)
6 = 217 (245)
7H7
3 = 125 (105)
7H7
3 = 130 (125)
7X7
5 = -108mV (-.6)
7AF7
4 = 42 (48)
6 = 40 (36)
5Y3
2 = 311 (320)
8 = 310 (320)
