Hook this set to a converter box and it should work just fine with an antenna. Since the CRT is very bright and you are seeing snow on the screen, the set's HV and signal circuits are in working order as well. A lack of snow on vacant channels would point to a very weak or dead tube in the tuner or IF strip, or else the AGC (automatic gain control threshold) control is set far too high for the signal area in which the set is located.

One way to test the set if you don't have access to air signals is with a DVD player or VCR. This test will confirm that the RF signal circuits are working as they should, and will also show whether the sweep circuits are working normally, although, as I said above, since you do have a bright raster the horizontal sweep must be OK.

BTW, I find it interesting that the CTC9 you got on CL was a "daily watcher" all these years--the CTC9 dates back to the 1950s and there are probably very few of these still in daily use.

I for one am glad you got the set before its former owner gutted the cabinet and put a plasma flat-panel in there. Well, at least he or she didn't make it into a fishtank, although who knows? The latter may have been their first thought before selling it.
