Hi there I replaced the C1 cap with this new one as per instruction of the Macplus PDF repair manual that is floating around the net. It says to replace it with a 50v or greater capacitor and that it HAS to be non polar. The only thing it doesn't mention is the UF rating and i'm not savvy enough to know if thats important in this situation or not.
The replacement cap is tiny, standing roughly at about 10mm in length and 5-6mm. The original was the as thick as my little finger lol I know technology has come along way in the past 20+ years, just surprised me.

I don't think it's C1 but it is important and could cause a DC current in the deflection coil to move the entire picture off to one side of the screen. > > I'm outta time right now.
