[trinescope]

If you're somewhere around Dallas/Fort Worth I'd be willing to do the alignment free of charge. I don't believe these sets were aligned somehow "matching" the tuner; in fact many set makers bought their tuners from outside sources rather than making the tuners themselves. Otherwise the alignment curves would show something other than marker frequencies in the IF range. Rather the IF was set up to manufacturer specs and the tuner done so separately and then the two should get along well afterwards. Tuners generally don't need much in the way of alignment unless something bad happened. All they really have to do is reject signals outside of the selected channel; all the other frequency traps and response shaping adjustments are in the IF strip.
