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 |

Michael,
I can scan the CTC-4 schematic from my RCA color service guide. I do not have Riders for RCA color past CT-100. You will have to gimme a few days to do this. Please contact me with an email address where I should send it. You can swap any of the glass 21" CRT's for the metal 21AXP22. These include 21CYP22, 21FBP22, 21FJP22. The CYP needs a 56K, 2W resistor to the second ultor connection nearest near the neck from the other ultor connector that gets the full HV. Fixin' up a CTC-4 eh? Good stuff! We expect pictures when completed. Note all the crt's except the 21FJP22 need to hide behind a separate safety glass. Rob Last edited by Rob; 07-17-2002 at 04:24 PM. |

Michael,
I can copy the Riders pages you need, just need to know if it's an early 4A or a late 4A. Let me know if you want them, it'll take a couple days to run the pages through the big copier. Chuck |
