[Elecraft] K2 Transmitter Oscilation Problem

[Ron Schuster]

Continuing saga on checkout of this K2.  Transmit goes to 20 watts at 5.1A.
RF out set to minimum

VALC = O DC V on transmit.  This may be right since the power is running
away?
U9 buffer DC V OK, NO RF RMS on transmit
U10 mixer DC V OK, NO RF RMS on transmit
Q5 Collector = 4 V RMS RF on transmit !!!
Visual checks are OK.

No RF in mixer may be right since Q24 is biased off by VALC?  Have looked
closely at T1, T2, T3.  They appear OK.  Not sure how to isolate this
problem??
