Discharging a VT100 CRT

[Julian Wolfe]

Well Well Well.

On closer inspection, it is very clear that the cap is what blew (it's
exploded and blackened on one end) is at C439, and the diode is CR408.  The
diode description in the maintenance print is aggravatingly overwritten by
the entry above it as it ran over.

The cap is a 75MFD, 6V, +75-10% Electrolytic cap

Where should I go from here?

different ones.

IIRC most were Ball Brothers.
