I got a new 21FP4C rebuilt CRT. A big thank you to El Predicta who donated the CRT for this project. He also donated a spool of solid 20awg white wire. Thank you very much for your generosity!
Here are a few pictures of the CRT.
I tested the CRT on my B&K 467. It checked out at 1.7.
And the Life Test showed a drop from 1.7 to 1.65.
Here is a picture of the straight gun. Yeah, I have to glue the base back on.
Again a big shout out to El Predicta! Thank you.
