earlier versions are really not so good.)
Unscrew the output jacks from the chassis and
separate the board from the chassis. The board
will be glued to the chassis.
It may require some extra work to pick the glue
off. Be careful not to damage the board or the
output jacks. They will be reused later.
Flow the solder to each transformer lead on the
output jack board and pull the lead out. Remove
the fastening nut at the star grounding post and
remove the output ERDUG¶VJURXQGZLUH
Clean up any remaining solder off the board to
assist in the installation of the new transformer
later in the build. Now that all of the leads are
free, remove the mounting bolts to seperate the
transformer from the chassis.
Keep the nuts & bolts. We use them for the new
OT.
Keep the
output jack
ERDUGZLWKLW¶V
ground wire
attached.
The new OT you are going to use will need a new chassis mounting hole as it is
almost certainly going to be larger than the stock VJr one.
Continue to use the hole closest to the edge of the chassis, and mark where the
new one needs to be drilled. You could drill it now, or do it along with the rest of
the drilling later.
