Hello dear community and especially mr.Pass

yesterday i have a trouble with one of mine zen4 amps(build already 5)
so what the trouble
one morning i just got ztx450 dead in one channel and full voltage instead of 1\2 on the output(the trimer resistor does not influence on output voltage)

so ive changed ztx450 to new ,everything is ok, ive adjusted the output by trimer to 1\2 and was almost happy, another power off\on and ztx450 again dead
what can do thins?
before that that chanel worked for month no trouble at all...
