Riders Copy Needed, CRT Question
Need Riders for RCA CTC-4A. Glad to share copies from my Riders I if needed, for TRK's thru '46-'47 sets for anyone needing them.
Also--are all of the 21xxx22 CRT's interchangeable? I know there are construction differences as to envelope, phosphors, etc. but will these sub for one another electrically?
Thanks,
Michael
