Just an update on the alignment.

I decided to check the tuner and work back through the TV. When checking the tuner on channel 3 it wouldn't align. The frequencies were too far off. I then decided to check channel 4 and sure enough the freq. were much closer, so I decided to use channel 4 instead of channel 3. 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.
