Thanks for the tips so far.  On #1, I've been advised that if fuse at F700
is blowing, check/replace Q705 & Q706.  Seems straightforward enough...until
I look up Q706.  The manual shows a picture of the location of Q706 and
calls it a 2N3792X.  But in the parts list is shows it as a 2N3792.  A quick
internet search does show both as distinct different transistors.  So, any
advice on which one is correct for a 6101 monitor?  I know I can just use
the same type as the one that was in there, but just wondering.

Joe
