[Drake] TR7A question

[Chuck]

I found (after several years of intermittent use) that my TR7A is 
slightly off frequency in xmit.
It is .5 kHz high. bnot a big deal I know but, I am anal enough that it 
drives me crazy. ;-}}
Without going through a complete alignment, is there a way of adjusting 
the xmit freq?
I checked the 10 volt setting and it was right on.
I set the  40 mHz osc and after several iterations have both sidebands, 
the fixed passband setting, and the calibrator in pretty good adjustment.
I thought the 40 mHz setting might be the problem but no.
Any advice would be appreciated.
Who does alignment of the TR7A and what does something like this cost?
Tnx es 73,
