Zenith Roundie

[tvcollector]

I'm about to make a purchase of a Zenith Roundie and I'm trying to make sure the picture tube is still good.. He said he tested the tube and the filament lights up as it should, meaning it's hasn't gone to air.. He said he tested it in 35 degree weather and does get response on all 3 guns and got around .2 ma on each gun, cold, and said they should go up considerable if allowed to warm up.. I figured I would get some input..
