Ron, I had a problem with one of my TR-7 rigs with the 40-MHz oscillator. To recenter the frequency to something reasonable, I changed C1006 to 39-pF (was 50-pF). Admittedly, this probably changes the feedback ratio but it did allow adjusting L1001 to frequency within its tuning range. This was on a radio S/N 6129 and was done 2009/10/27. The radio is still operating properly as far as I can determine (no realignment since but no measurement of the oscillator frequency either).
73, Bob K9JU
