Not sure where to go from here. The video output board is about a year old (it was NOS).
Does this info help?
Thanks

OOPS! Brain was absent on the 9-121... I meant the 9-151. That was a System III board, but showed up in the few late Chro II sets with inline tubes.
Let me take a look at the manual on that chassis to refresh my memory... Might not get a chance til tomorrow, but now I need to know because it's bugging me
. It was definitely an electrolytic; not one of the paper or mylar caps.
