Channel 4 aligned perfectly with the waveform and frequencies where they should be.
Then on the the IF section. Again the IF section aligned great with a correct waveform and on frequency.
I used a meter to align the first step in the 4.5mc audio section. But the 2nd step didn't work out so well. I never could get the meter to zero out. I hooked up the sweep generator and o'scope and peaked per step 1, but never could get the cross over pattern in step 2. I ended up just tweaking by ear.
Oh, I also used Wallace Teleaides to check the run updates and some cures for other problems. Looks like my TV is from run 5 and I installed the retrace mod, both vertical and horizontal picture was too large so I followed the steps to reduce those. I added some resistance and shorted out another resistor.
All-in-all the TV is playing very well. The picture tube isn't as bright and clear as I would like it, but it never did test into the green very far. I'm happy with the results so far.
Stay tuned for final pictures and report.

I don't think there was as many 14" rectangular sets built at the time, so the 14CP4 isn't that plentiful. It seems, Admiral and a few others came out with sets using the 16TP4 rectangular CRT, just a little later.
4,5 years later, the 14H/QP4 came out for smaller screen portables, like the Emerson and GE. They seem to be more plentiful and they use the identical glass, but are self focusing.
