Jerry,

Are you referring to the "Overload Detector" being tripped?
If so, try adding a .01 uF capacitor between the base and emitter of 
Front Panel Q7.
It seems some 2N2222s are a bit more sensitive to noise on the overload 
detector output line.
I know of at least 2 that were cured with this fix.  Very few 
transverters have this problem, but for those that do, it is an easy fix..
