Funny that the conversion kit was only $15. if that were now, would probably be $200.

I was referring to the set with the AX to the CY conversion. It might've been a service contract replacement. Color CRT rebuilding, in the late 50's, wasn't as common as B/W rebuilding. Also, the mortality rate of rebuilding any metal coned CRT was poor and the prices reflected it. They were a lot more expensive, than they're all-glass counterparts.
The 24's, 27's and 30's, only had a six month warrantee.
