Sorry, the first board is 9-155-20, and the upright flyback board is
A1-1341-6 (the only # I could find). I will try to get the model #
tomorrow. TIA.

Kevin,
At the very least we need to know the board numbers. (9-XXXX).
I suspect there are a lot of fixes in the data bases for as old as this
set
is.
