A while back I picked up a 3" Heathkit HO-10 monitor scope. After using for a bit it devolped an intermitant and it turned to be the solder connections at the socket. Carefully removed the base and scraped all the copper wires til they were nice and clean. Solder on some long peices of thin wire like #36 to wires coming out of the crt. (3RP1) Used those to guide the base back on to is proper place. Solder it all back and has worked great ever since. The hard part is remembering which ones go where. Getting them in place wasn't bad at all.
