I had a 121J which was a good set but developed a red short in the crt. These are just about my favorite RCAs of the post-1970s ones. Does yours have the auto brightness with the photocell? I think all colortraks came equipped with the feature. So cool that you scored the matching VCR BTW! Nice setup,
EDIT: If you have the original remote, thats just awesome... I'd love to see a picture.
