****EDIT****
I compared the wiring diagram in the Owner's Manual to the Sam's and the Sam's is indeed wrong. I figured I'd leave this post in case someone else encounters this issue in the future.
I just realized that I forgot to hit post yesterday regarding V7 (6CM8). It is not wired as stated in the Sam's. Here is what is different:
So V7 is kind of funky but I figured it out. Pin 7 is the only odd man out. Everything else is good.
1 and 6 are reversed
2 and 9 are reversed
3 and 8 are reversed
7 shows it should have the same leg as 6 (which is wired as 1 《150vdc》) but it is actually getting 15vdc from the square 30mfd cap. As a result the keyed value is half of the Sam's ( 17.2vdc vs 30). I'm not sure if it is relevant or not. Below are the wiring descriptions and new numbers.
V7
Pin 1 : 176.5vdc from 30 mfd cap (triangle)- tied to R4 modulation pot
Pin 2 : 15vdc from 30mfd cap (square) to 10 meg resistor
Pin 3 : runs to squelch knob
Pin 6: 1 Meg resistor to V8 Pin 8
Pin 7 : 15vdc from 30mfd cap (square) to 82k resistor
Pin 8 : 4.7k resistor to ground
Pin 9 : 47k resistor to 3.9meg resistor and audio line to mic socket.
V7
Pin 1 : 80 = 75
Pin 2 : 3 = 3.6
Pin 3 : 8 = 8.5
Pin 6 : 15 = 15
Pin 7 : ? = keyed 17.2, unkeyed 15.5
Pin 8 : .8 = .9
Pin 9 : 0 = -.1
It all looks original. No modifications appear to have been made to the radio.
