I'm thinking of doing the VGA mod to my Color Classic A/B. I read that the mod changes the horizontal scan voltage from 60V to 84V.  I have  a couple of questions:

I haven't recapped my A/B yet.

Should I recap it before doing the mod?

Does raising the voltage stress any components on the A/B? 

Could I compensate for that during the recap of the A/B?

Thanks
