Mac SE: ?: Video board width adjustment

[Addicted]

Hi all, dusting off an SE I recapped oh, three years ago. The video needed readjustment, and after correcting the height I noticed that the vertical height coil seems to have no screw tap in there. I can't tell for sure - does it accept a (plastic) Allen wrench instead? Or is the plastic screw-cap missing?

I believe you need a 2.4mm hex key for those.

Ah, thanks. As suspected. While I have a set of ceramic-shaft RF screwdrivers, I finally tossed my all-plastic CRT/TV tool pouch years ago. Now I need the hex tool it had, the one I never used. Time to improvise. Whittling down a cheap bamboo chopstick is Plan A
