I went to see the set today.
CRT is a RCA Colorama 21CYP22A, date code 6643, installed on 4/30/67.
Initial readings were all in the red, so I boosted filament voltage 10% for a few seconds and saw an increase. Went back to normal voltage and after 15 minutes blue and green guns emission are in green region and red is on edge of green region. Blue gun shows a little G1 leakage, within spec.
The set is upstairs in an old building (1880) on Cherry Street in the old downtown area of Rochelle IL. This upstairs looks like it was a boarding house or?? Downstairs was probably a saloon, as I was told they used to call this section "liquid avenue" for the number of saloons in one block. Now it is a mission.
They said one of the bidders is from Germany.
If you do get it, make sure someone removes the back and takes out the few loose spare tubes (in boxes) that are laying loose inside.
