 From time to time I have noted discussions on the power supply
 problems of the Mac+.  Mine has now developed the symptoms
 of an intermittant expansion/contraction along the horizontal
 display axis.  Occasionally the horizontal drive will collapse
 completely and I'll just have a (bright) vertical line.

 When I pound on the case, the video comes back, so it sure looks
 like there is a bad solder joint somewhere.  I looked at the 
 analog board closely, but couldn't spot any obvious problems,
 nor were the electrolytic caps at the "top" of the board 
 obviously bad.  So I just swabbed as many connections as I could
 conveniently get to with tuner cleaner, reinstalled the board,
 and powered up.  It looked good for about a week, but things are
 now deteriorating again.  Could someone who has successfully treated
 this tell me *where* your bad solder joint was?  Is there a 
 particulary suspect connection somewhere?  Also is it true that
 authorized mac service shops will not exchange, but will only
 replace, mac analog boards that have been obviously worked on,
 regardless of how minor in nature ( a persistant rumor here ).

 My mac+ is now about 4 years old, and I'm thinking I would like
 to keep it going until I find out if there really is going to
 be an SE/30 in 1st Q,89.  

 Any suggestions gratefully received...
