removing small screws in side rails and the rear bottom panel lip. This is a properly wired panel, which saves
you considerable time. Correctly wired panels have long transformer leads that allow rear panels to drop
without removing any wiring, with the exception of output coax:

Note:
Incorrectly wired panels will not drop without unsoldering multiple transformer wires, and perhaps coax
and other leads. It’s advisable to take a picture of the panel with wires attached to aid
in reassembly of the
panel. Be careful unsoldering leads. Leads are accessible through a plate on the back of the back panel. Use a
large iron, and have a solder sucker or solder wick handy! Use a large hot solder-wetted tip on the wire ends
that stick through the boards, so you can get on and off the solder joint quickly. Do not linger and overheat the
