Looking at the sams,
uses a 25AP22
only has two IF stages
uses 6GH8s for everything, video, the enitire color circuit including the r-y/b-y/g-y amps
has about 8 6GH8s in it
The rest looks about the same as the higher end RCA color sets.
uses full power transformer
The CTC19 is a metal table top. I have one, havnt got around to working on it yet.
IIRC the CTC20 was a late roundie.
Its a small chassis, the IF and low voltage power supply are on the deflection board, the audio out is on the chroma board.
Only 2 boards instead of 4
