Funny thing happened on the way to the TV convention. I found this Admiral roundie for $20 at a thrift store. It is a RCA CTC 11 clone set. I would put it at 1961 for a year. The 21FBP22 in this set is awesome!!! I put it on the tester and it popped right to green on all three guns!!! The lytics will all need to be changed. The tube and CRT filaments light but no raster. The flyback is also good in this set. I am glad I decided to thrift store hop on the way to the convention!!!!
