The mechanics are quite simple and can be rebuilt using simple
tools.
I have worked on everything with a cordless screwdriver, it
does not need a large mechanical workshop. A tip on the side,
the front panels are from Schaeffer and the threaded bolts
offered there are only glued in, that does not really hold! I
have the ALU angles additionally glued with UHU Endfest to the
front panel. Curing is faster at 45 minutes at 60 ° C in the
oven.
