Anyone familiar with a Symphonic TPS 200?

[Mark]

I have an old TV/clock/radio combination unit that was my fathers, I'm guessing it was from the late 60's or early 70's. It says it is a Symphonic and the bottom plate lists the model number as "TPS 200". The TV is about 3" diagonal, maybe a bit less, and is black and white. Try as I might I can't find anything on the internet about such a unit. The closest references I have found so far are for a TPS 30, TPS 301, TPS 5011, and a TPS 5050. I looking for any information I can find on the unit, including whether it may have any value as a collectible. Has anyone ever heard of it or know where I could go to find information?
Thanks!
