You did not show which Tr geting hot. If HOT get hot
it will be blow out again in the very near
future:....you should check the coupling cap about 1uf
or 0.47 uf couple H drive pluse to H brive TR. change
a new one. HOT will not be hot.
    If the pin output TR hot change the pin coil that
feel to this TR. This coil had been over heated the
copper wire probable be shorterd some portion  so that
over current to Pin TR and the pin correction effect
is not good or failed as before.


Thank you
