When working with my CTC-5 last week I noticed that all the service literature I have says between 19.5 - 22.5kV at the CRT anode. My CTC-5 is putting out exactly 20kV.

Why do I constantly see folks complaining about the CTC-5 not putting out 25kV when all the original service literature says lower than 25kV for this set is normal?

SAMS for early CTC-5 says 22.5kV
RCA Original Service Manual says 19.5kV
RCA Original Setup Manual says 20kV
SAMS for late CTC-5 says 22kV

See attached snip-its from some of that literature.

Just wondering as I have limited experience with vintage color sets.

Thanks.
