Mixer amp
With age,humidity or temperature or whatever, the screening card lining the
inside of the plastic case can curl up and touch solder and traces on the
IEC sub-board, aluminium side to mains voltages. Cut away all around that
corner on the rear and side card.

The EMX 88S has proper rigid metal work around that IEC area

For us folks on the west side of the Atlantic Ocean, what is a
screening card?

*****

The lining put inside plastic cases to simulate metal cases as far as RFI
out or in , in in this situation.
(almost as good as the pub sign painter having to change the kerning
between the "Fox" and and and and and "Hounds").
Something like a composite of card and aluminium foil so high probability of
differential dimensional changes, ie curling

Whats it called over there and I'll add to

Typically what you Brits call "screening" we call "shielding". I think
most folks here would refer to that as a shield of some sort (RF,
electrostatic, etc.)

So what we call a valve screening can would be a tube shield in the US ?
