    Well I worked on the KLH Fifty Five tonight that I posted about earlier.
    Turns out it is in fact only in one channel which simplifies things
    greatly and I tracked it with freeze spray down to a transistor marked
    K40. I assume this is a 2SK40? I couldn't find much useful info but it
    seems this is an N channel fet. Anyone know the pinout?

    Well I just happened to have a few ZVNL11 mosfets in my stash so I
    popped one in using the same orientation and it worked! I should
    probably scope the outputs and see how they compare from one channel to
    the next but it sounds pretty good to my ear so I think it'll be good
    enough for grandma. Nice to have it fixed finally, it's been acting up
    for over a decade and was unusable the last couple years.
