Re: video problem on Space Duel

Rodger,

Good idea. I checked for ripple and couldn't find any. If I put my BW board in this
cab, it works fine. If I put the SD board in my BW cab, I have the same issue.

I replaced 3/4 of the TL082's no change, but maybe could be the fourth?

Could my pots just be bad?

Thanks,
JB
