Rca 721ts

I just picked up tonight a RCA 721TS for $95. I was a little hesitant on that price, but it seems they go for that or more on ebay. I didn't take a tube tester, but I checked the heater pins on the CRT and got good continuity while I was there.

It belonged to a lady that recently passed away and her son sold it. It was in the family since new. They said they stopped using it in 1959. It looks like most of the tubes are non-RCA replacements except the CRT. I hope it tests well.

One question: Is the tuner supposed to have detents and clunk for each of the channels?
