Sony 25" PVM2530 find.

[Eric H]

I tried hard to leave this one at the store but my resistance wore thin and now it's in my van.

This is an Industrial Monitor from 1990, I don't think it even has speakers but it has some pegs on the sides to hang them. I remember wanting one of these really bad back in the day!

Hooked it to a DVD player at the store and it displayed a good image with a strong looking CRT, I hope to use it with my Laser Disc player using the S-Video input.

Not sure what the cost was back in 1990 but I got it for $25.

Nice score. I'm sure it's built like a tank and there's no telling what it cost when new.

I think I have the 19" version of this set at my ballpark. East Coast guys come and get it.

Nice find! I wanted one in the worst way also, but never seemed to get hold of one. Now you need the 500-lb 43" tube version; PVM-4300 ;-) .

Charles, are the tubes in these as bad as the consumer 25" ones they used in the consoles?

Definitely not. The dreadful 710AB22 was the 26" console tube, and the one in the PVM was a fine-pitch, high-resolution industrial grade tube.

So what went wrong with the 26" jug? Bad design? Poor processing? Was this perhaps an early example of San Diego production?

About 25 years ago I was told the problems were caused by gun contamination from the perfume/cosmetics worn by the women who assembled the tubes, and the problem was solved by forbidding such aromatics on workers. I would be interested to know if anyone else has heard this, or was I fed a plateful of guano

Seems unlikely since the tubes are baked at high temperatures during evacuation, unless it somehow damages the Cathode before they are assembled?

I know where one of this same set is locally. It's running just fine. I replaced about 15 capacitors in it about 7 years ago for its owner. It's got a fine picture, and runs about 5 hours a day.

It has the OEM speakers on it.

I have fond memories of the bad 26" tubes in the console Sony's.

[Eric H]

What was the failure on those tubes, short lived or shorts?

I know some Sonys from the 80's had short lived tubes.

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.

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.

I still have to drag this Monitor in the house and see how well it works.
Grey scale looked good though.
