[Drake] TR7 Alignment - 8.05 MHx Oscillator

I'm trying to do an alignment on my TR7 and am having a problem trying to
set the 8.05 oscillator.

Adjusting C1030 and trying to obtain 5.645 at pin 40 of the PBT/Refernece
board, the best I can do is 5.6457. The 13.695 oscillator is right on.

I have removed capacitor C1029 completely and have the adjustment on C1030
at minimum capacitance. This is possibly telling me that the 8.05 crystal
has shifted somewhat.

Has anyone else been there?

Any suggestions on this one.

Thanks.

Jim
