I'll be hooking up my signal generator tonight and testing the IF section. I'll also try the 2nd radio test to see if the oscillator is working properly.

Also, I went in and replaced #22. It was listed in the service bulletin as a 0.01 uF cap and that was what I had installed, but there was an asterisk. The asterisk stated that after Run. No. 10 to use a 250 pF mica cap. I had originally removed that cap and I forgot it was a mica. I then fired it up and checked the SG (pin #3) on the 6A7 and got 42V instead of the original 180V. I don't have my Excel spreadsheet so here are the voltages:

78 R.F.
Point P (pin #2): Expected = 71, last check = 81, tonight's check = 204
SG (pin #3): Expected = 91, last check = 90, tonight's check = 42
K (pin #5): Expected = 2.1, last check = 3, tonight's check = 1

6A7
Point P (pin #2): Expected = 240, last check = 260, tonight's check = 270
SG (pin #3): Expected = 91, last check = 0, tonight's check = 42
K (pin #6): Expected = 2.2, last check = 3, tonight's check = 6.2

78 I.F.
Point P (pin #2): Expected = 242, last check = 266, tonight's check = 272
SG (pin #3): Expected = 91, last check = 91, tonight's check = 42
K (pin #5): Expected = 2.3, last check = 2.3, tonight's check = 0.81

85
Point P (pin #2): Expected = 102, last check = 111, tonight's check = 112

1st 42
Point P (pin #2): Expected = 240, last check = 264, tonight's check = 263
SG (pin #3): Expected = 250, last check = 272, tonight's check = 276

2nd 42
Point P (pin #2): Expected = 240, last check = 258, tonight's check = 268
SG (pin #3): Expected = 250, last check = 272, tonight's check = 276

80
Filament 1 to Ground: Expected = 300, last check = 319, tonight's check = 328
Filament 2 to Ground: Expected = 300, last check = 319, tonight's check = 327

It should be noted that I used a different multimeter for the above readings. I had problems with the one I was using before so I borrowed one from work. It is a calibrated Fluke 787.

Also, I am using a variac with an analog meter so I think slight differences in voltages from the last check can be attributed to not being precisely where the analog needle was last time.

Again, I only changed the 0.01 uF (#22) to a 250 pF mica. I touched nothing else.
