RM301 used in KV1733R & KV1930R maybe others.
The Craigs list set is an Ecconoquick ( fast warm-up CRT )
& is newer. Its the last generation of SG613 sets.
Very neat modular chassis. I got 21" one at the dump with a vert
problem & ran it a year before selling it for $200. Wish those
days were back.
