Had this puppy running great for about a week and WABOOM
my Major Havoc (Tempest Conversion) just started acting up again.
it powers on and plays but the vector lines are all out of whack.
after investigation tweaking the X center R39, X size R34 and X Lin R38
yield absolutely no results.
As per the Major Havoc service pack 252 pdf all three adjustment pots
are in the same circuit so I am assuming my problem lies therein.
all others pots react so I guess my problem is in that circuit.
This is sorta as far as my board repair knowledge takes me other than just
pot luck un-soldering and replacing IC's and hoping for the best.
any help/advice would be greatly appreciated
Thanks in advance
