Sorry I am new to Teletype restoration, what is the LESU? Is this another
term for the circuit board that carries the Selector Magnet Driver? If so
there is no insulating paper of any kind behind that board in my M33. I am
guessing I should add some even if that isn't part of the design as there
are wires close to or touching the large soldered area on the back of the
board.

Regards

Rob
