I vote Zenith 24NC31 and Philco 17MT80. The RCA CTC20 had too many 6GH8's and RCA's infamous flyback to be a better set.

Though Sears and some others may have had one, Motorola, Sylvania, Emerson, Westinghouse and Admiral did not make a roundie later than 1965. My knowledge is limited to my service info and limited exposure. Most round CRT color sets hit the curb just before I started the hobby.

There was a 1968 Magnavox Round color chassis T938 (Sams set 1037). I had one long ago, it had the sick video-color look that many mid-60s Mags were known for, that sold many a CRT. The REAL issue required some advanced troubleshooting with a scope to find the bad parts. I was not so patient then.

The only other one I know of was 1966 General Electric's CB21, which was not a clone but a budget version of the CB23 and CB25 which used the troublesome 23EGP22 and much better 25AP22 rectangular tubes.
