The sams on an admiral color set ( 1963 ) just lists the admiral fly number which is 79D102-501 , since this is a RCA CTC-12 clone the RCA fly number is 112820 , thats incase nothing shows for the admiral part number , anyway if anyone can look please

thanks
Mike

Lets go with the Admiral number first..Thordarson FLY-273, and you're right the same replacement listed for the RCA.

Triad-Utrad replacement is a D-303.

Most all of those 60s rca roundie flys are interchangeable. That includes sylvania magnavox philco packard bell all the clones etc. It all comes down to you having the aptitude and resources to figure it out and make it work. You may even have to disassemble the fly and move the doughnut

Don't know if this will be of any help. You can left click on the image to expand it.

I've got one of the non-clone Admiral sets from 63 or so, I used a FLY-273 and it worked just fine.

There is a flyback sub book on sale on ebay in the flyback category

I saw a few manuals listed but look under "Thordarson".
