Final assembly

10. DI bBoard installation

Place one 1.2mm plastic spacer on the jack sockets and insert into the front panel while fitting the CN2
connector pins into the socket on the preamp PCB. Screw in the front nut through the beveled front
spacer with an M12 socket spanner.

11. Closing

With cutting pliers, cut the 4 lugs attaching the
transformer opening. Cleanup the cuts with a small
file.

Attach the cover PCB with four M3x6 countersunk
screws.
