Got back on this this weekend, but not as much as I wanted because I was called on to photograph the kids at the neighborhood block/Halloween party. Anyway, I couldn't get the 1st-2nd IF coil tuned right this time until I discovered that somewhere along the way I had switched to an un-terminated input cable - duh!
Now have to find out what I have been doing wrong in the over-all IF alignment.
One more thing: terminal "C" on the video board is the first video grid and should be grounded during alignment. Terminal "C" on the IF is filament supply and should not be grounded unless you like the smell of burning jumper wire insulation.
