AdamAnt316, this was Sony’s earliest attempt at a larger tube size. I don’t think a 19” size came out for another couple of years. First color Sony was the 7” KV-7010U with the chromatron tube than shortly after that was KV-7010UA and than this had the trinitron tube. After that they only had a 12” size. So when the 17” size came out that was a big deal. Sony also had a 15” size. And as there technology progressed we saw larger and larger sizes. 19”, 26”, 30”, and upward. Smallest tube size a trinitron ever had was a 3.7” KV-4000 line that was released in ‘80 I think. Anyway, you have a real nice keeper representing an interesting time in television. May it bring many enjoyable hours of watching enjoyment for you.
