Width & Focus in DuMont RA-103

[Phil Nelson]

The width coil was not taken out of circuit. I temporarily unsoldered one of its leads at the flyback and tested it, as well as the 5-6 connections on the flyback. Neither is open.

I will look at the WW resistors next.

Look at how far off-kilter the focus coil has been cranked. Kosher? (If not, why would they give you adjusters with that much leeway?) It looks like none of this stuff, including the CRT, has been touched in ages.
