That way, you have a 'target' to walk the IF adjustments toward.
(Ch 3 carrier is 61.25 mc.)

I was hoping you'd explain to us how to do that.
Also a B&K 1076 or 1077 Television Analyst would be really handy right now too. With that he could inject the Analysts IF output directly into the sets IF and manually sweep through 24MC, so he could see exactly where the TV's IF response appears to be optimized for best sound and picture. A very handy and educational tool for anyone planning to stay in the TV restoration hobby.
