Blankety blank, *#&$%&^# RCA

[Eric H]

Ever have one of those projects you just feel like chucking in the garbage can?

I've been working on this RCA 8" portable for a few weeks off and on, fully recapped except for the filter can but it seems OK, biggest problems have been getting the vertical to work right, particularly getting a good lock on the vert hold.

I got it good enough to call it a day and started putting it back together, put the shield back over the neck of the CRT and put the chassis back together and turned it on, no vertical deflection, a quick check showed no B+ to the plate, seems I managed to nick a hair fine wire on the Vert out transformer with the metal CRT shield, the stupid wire was supposed to have some insulation protecting it but didn't for whatever reason so it broke right off.

Pulled a transformer off a spare chassis I have and slapped it in, good raster so I went ahead and put the chassis back together again, adjusted the Ion trap, good raster, good snow so i turned on the signal and... It's upside down and backwards!

Guess the transformer is a little different, possibly it's from a chassis with the 6CG7 instead of the 6CM7, anyway I'm hoping I can fix it by reversing the more easily accessible wires.
