Does anyone happen to know the exact part number of
the flyback
transformer in the DEC VT100 terminal? The VT100 in question has the
'DEC' type video board, not the 'Ball' type. Is there a matching
HR-Diemen or equivalent part number?
Oh, and questions concerning another VT100: What may cause a bad
geometry of the picture on a VT100 (slight trapezoid and pincushion;
Philips CRT)? The only adjustable magnets are the two sets of rings on
the neck, one for the position and one for the focus (it's a
magnetically focused CRT as most monitors are).

We used to position magnets along the sides at the front of the tube to
correct the trapezoid/pincushion. 1/4" x 1/4" x 1 inch magnets.
sometimes had to use several on each side and the top and bottom to
square to image. (if we had to we'd break them in half as well)
Hope this helps.
