They'd go gassy with low emission; sometimes in less than a year. Sony put out an upgraded tube in the early 90s. I forget the number, but it was something like A67JHG00X. I bought a brand-new KV-2654R in '83ish, and took it under warranty in a few months for a new tube. By the time the 26" line was 10 years old, I hardly ever saw one with the 710AB22 still in it.

I finally found time to wheel this into the house and hook it up.

Hooked up a DVD player and popped in some Scooby Doo and it works great!
The CRT seems to be really strong, great color and lots of detail, the DC restoration is excellent, dark scenes are dark (check out the black background behind Scooby) and light scenes are light.
One issue is that you can't tell if it's on or not when there's no signal, the set was on when I found it at the Thrift, for how many days who knows.

It's not a fine pitch CRT but the Comb Filter gives it a really fine picture.

Hooked up a pair of Minimus 7 speakers, sounds great but their magnets messed up the purity, but this monitor has a manual degauss button and it fixed that right up!

The controls are along the edges of the screen, they are invisible until you press the control button to illuminate them.

This is a keeper, just don't know where I'll keep it, maybe I'll find a gutted 50's cabinet to install it in. :scratch2:

Here's some pictures, hard to do justice to it with these though.

Hard to go wrong with a Sony monitor that starts with a "P" or a "B"...
Happy viewing.
I think there were some small RS speakers that were magnetically shielded. It's funny how that was a temporary 10-15 year need. LCDs don't care.
