Now I understand why I was getting the FM radio, that means earlier on ch 3 I must have been picking up something around 108 MHz.
I tried connecting the frequency counter to the tube shield, it still wouldn't give a good reading on anything but ch 1-3.
I tried adjusting for sound on each channel I could receive over the air, + the DVD player on ch 3, so I adjusted channels 13, 11, 9, 7, 5, 4, 3, 2. I can now get sound on channels: 5, 4, 3, and 2 - but with some buzzing. I still can not get sound on any of the other channels, but I did get some buzzing.
In order to go through the whole procedure with all the channels I'm either going to have to find a frequency counter that will work with the lower input level, or I saw another procedure in the service manual which just involves hooking a VTVM up to the sound discriminator but with that I need to find another signal generator that goes all the way up to 215.75 MHz for ch 13, this one I have goes no higher than 50 MHz.
