Leroy, I'm headin over there this aft. how do I check the yoke,
any idea on ohms?
I don't think its that, or at least there must be something else as
the hum I hear at turn on is through the speakers, I was going to un
solder the audio ic and see what happens because I know some sets will go to
shutdown if it shorts, but thought I better check before I cause more
damage.
