Now the reason I took a break from other projects to poke around with this set, is that a potential replacement CRT just arrived
Out of the blue I was contacted by an online friend that had an untested, unknown CRT and asked if I'd like to have it. I figured it must be a 10BP4 based on his photo so I said sure.
It was well packed and arrived intact. It sure is a 10BP4 and RCA Victor branded too.
I crossed my fingers and fired it up. It tests like new
Now how to install it ?
I removed the bolts from the chassis and started to slide it out of the cabinet. Huge mistake
Luckily, disaster was avoided as I noticed the heavy CRT front drop down and stopped before the neck snapped off in my face
Just like in the 630TS, the CRT must be removed from the front as it's only supported by little brackets attached to the cabinet. I consulted the service info and discovered the trick to removing the front of the cabinet.
It appears to be a replacement from 3-3-1948. I guess the original didn't last very long.
I tried every trick I could think of to resurrect the open filament in the old 10BP4 with no luck. Very frustrating since the getters are nice and shinny and I can see the intact filament wires running down into the gun.
