I do some repair work now and then and I got a HF transceiver
that I once replaced a DTC114ES digital (pre biased) transistor.
It didn't appear shorted, it just wouldn't turn on. I just got
a call from the owner and from what he's telling me and from what
I can gather in the schematic, it appears that maybe another
digital transistor of the same type has failed, but only in a different
location?
This unit is rather old, it uses through hole digital transistors. Was
there some fab problems back then that made those fail internally over
time ?
