What I know is that it is a higher end model, the others from that time period have tubes. ALL are well built but the set you have was almost 400 bucks when new. Excellent score Sandy! I've been looking for sets like that for some time now to no avail. I'd love to have the tube sets from the era as well. I did find one at a Chicago estate sale a while ago where there was a 1966 Panasonic which I REALLY REALLY wanted but Doug Harland got that one, he left me a 21" '71 Panasonic at the sale that I purchased and was really happy to have but then before I loaded it into my car he offered a monetary amount that could not refuse (more than 3 times what I paid) and I sold it. Now, I wish I wouldn't have. The very GOOD amount of money is gone, the set would still be with me and now the search still continues.......
