What kind of crt has it? Is it a Permachrom one? Is it a 110 ° deflection crt? - In Germany we have color tv since 1967. The best tube (hybrid) color sets were built in 1968-1970. Before that time the crt's were weak and the chassis were overloaded. The second generation with the 90 degree deflection Permachrom-crt's was the best. I never saw a bad or weak 90° Permachrom crt like the crt's of the years before or after them.
After 1970, the manufactores changed to 110 degrees crt's. That was too much for tube-based sets. And 1973 came the change to solid state, with many problems too. The first reliable sets after the end of the 1960's appear at the end of the 1970's.
With respect to my comparison of the ctc-5 to a Permachrom-PAL set: This was only a demonstration. For daily use I would drive the set with lower contrast control and brightness. Otherwise I'm worried about lifetime of the color guns in the crt.
The only full tube color tv set in Europe was built by Philips in Krefeld in 1964, the 21KX100A with the K4-chassis, and it was destinated for export to Canada. It is the only European "Roundie". Some K4's survived and one can find them in U.K., the Netherlands, Germany and in Austria, as far as I know.
