[TenTec] Omni C Questions ( Maybe OT )

[Tim Long]

  I just wrestled with that problem a few weeks ago...my Omni was dead 
on 80.  My problem was broken traces on the VFO Mixer board underneath 
the crystal socket strip.  I re-flowed the solder where it looked like 
it needed it and the problem was solved.  That board is probably the 
most difficult to remove and I am very glad I called Ten Tec to find out 
the removal tricks.  I'll post them if anybody wants to know.

Called Ten-Tec about another socket assembly, of course that is unobtanium.  They gave me the standard lecture about thirty year-old radios being unrepairable.
