whats interesting to me it does not seem to have a color osc tube, so no zero beat adj or other freq control issues to fight. Looks like the same demod system as used on the porta color, just amp up the burst and let it ring. The chassis layout is like a CTC-15, but the PCB are def not RCA, the chroma and sweep boards are swapped (sweep near the back of the chassis) 3 tubes on the chroma (uses a compacton triple triode for the color dif amp). The audio is on the deflection board and the space where the audio board should be is pure power supply, just resistors/diodes (full wave)/thermistor.
bigger than normal speaker. Has had some sevice (PS board has some replacement resistors tacked on top).
Odd, red loop of wire coming up from the back of the PS PCB, looks like it jumps the thermistor, looks factory, and has been cut at the top. Maybe a factory option to use in sets that don't have a auto degauss? with the loop intact the thermistor would be bypassed? this set has the degauss hardware.
