The Baby Will circuit board, tone potentiometer, and the new output transformer

Always verify you are using the latest version of the drill plan posted on

If you can not print onto 11x17” paper, you can take an electronic
version of the drill plan to Kinkos. They will print it professionally for
under $1.
Print out a copy of the VJ Conversion Drill Plan. Make sure it is printed to scale.
Cut away the unused
portion of the drill plan as
shown.
Align the drill plan to the
chassis using the
alignment holes
indicated on the plan.
Affix the plan to the
chassis with a generous
amount of tape or
Elmer’s white glue.
