Picked up a CTC-4A

Went to an estate sale the other day and found an RCA CTC-4.
It's the "Director 21".
I've never had a color set this old, and have not attemted to power it up. I did take the back off, and noticed something has been burnt right in front of the yoke, unless it is a section of the yoke.
Otherwise, set is in good condition. There was a service tag inside and the address and name matched the original owners of the house. Set was plugged in, and still hooked up to an outside antenna when I got it.
The set was in the master bedroom.
In another bedroom was a CTC-28 set which I also got. Fired that one up, and it works.
