If it is a GE BEFORE you plug it in check the safety cap.
Usually the HOT is on a separate heat sync that is held
on by 4 plastic pins. Remove it & the cap is there. If its
the original white job replace it 1st. They went L & R on the
GE's & instantly blow the HOT. Yokes also shorted & the vert
module + & - rectifiers would short, cook the FBT & HOT.
