Bent away from the chassis, but not creased. These facia are relatively

If you heat it it will discolor. Just glue it. I had the same thing
happen
to an old Master Lead 50 that I used to own. Glued it and that was the
end
of it.



On the older amps and the valve tops, the cabinet holds the fascia tight
against the chassis, on the newer stuff it doesn`t and the gold panel
can bend as you withdraw the chassis. I spose the correct way to do it
is the remove all the knobs etc, flatten the panel by rolling it the
'wrong way' then refit it. And be more careful removing the chassis next
time :^)

This was pre-existing , I tend to use a couple of strips of celluloid at the
ends on replacing, when tight, to reduce problems of catching.
I am thinking of chamfering, edge relieving, the aluminium edges slightly
with all these sort of clad facia amps with an old carpenter's spoke-shave
or plane or even just the corners back an inch or so - any thoughts ?
