RA103-D has strange issue(s)

[David Roper]

I recapped this set a year ago and it's still not back in the cabinet. When horizontal hold is adjusted for greatest stability, the two fields are misaligned at the top of the picture and wave madly. If horiz hold is adjusted far enough toward the left, the waving can be made to stop entirely, but the sweep cannot sync by itself at that setting. In other words, if adjusted for best picture, the horizontal will be torn from either a cold startup or just momentarily tuning away and then must be manually re-synced.

The set is also extraordinarily prone to drift of the gain, showing excessive contrast when first turned on that fades quite a bit over the course of a half hour or more.

I'm also curious about others' experience with similar Du Monts as to their DC restoration. I would rate this one as quite poor, about on par with that of a GE locomotive. It's an almost impossible thing to quantify, but I know good DC resto when I see it and I don't see it in this set.

Any help appreciated.
