interesting point...

I recently assembled some cap kits for the vectrex..

after capping my vectrex, i'm noticing some wobble on the entire screen,
slow-ish moving..

I went for the panasonic high frequency, high voltage 105c caps too..

i don't suppose i paid much attention to the picture before i capped it, but
this cap kit does cover everythign on the monitor board, which includes the
early stages of deflection too.. i'm just wondering whats up.. either i'm
looking too closely at the picture or it installing the cap kit has had a
reverse effect :|
