XTC isn't easy amp to work on it. Especially removing pcb completely from chassis is quite tough. But fortunately it is not neccessary. Every mod Marvel done to my amp took place without it.
Partially lifting up the board is enough. To do so You got to remove preamp tubes, then remove knobs, unscrew the pots, then unscrew the pcb, disconnect loop wire and desolder wires that link powerboard with main pcb.
Then You got to raise the pcb angularly, the way where the pots are pointing down to the chassis and the inner (back) side of pcb is raised. You will have it angled and there will be space to mess up with it.
ONLY NOTE that channel diodes are glued to chassis. Don't try to remove them, it is possible to work on an amp without doing it.
