Well I stoped by the two old repair shops here in town today, neither of them had any old sets around. One did say he had some round CRTs still. I asked him if they were new ones, he said they were pulls that tested good way back then. I told him I might come back for them. How much are used/good CRTs worth ? to get them I'd probably have to buy all of them...I tried to gather more information but he wasn't talking much so I ended up making it quicker than I planed.
