Looks like 19" magnavox's i'm considering for a couple tube swaps. Anybody have any problems with this brand? i'll have to check the pin outs and deflection angle of course but was going to offer $20 for all 3.

As long as they're 19" there's a good chance they're compatible with /something/. Make sure they're actually 19" though. I've grabbed TVs before thinking they were 19" and they were 20".
 
I have one that looks like that here. It has a manufacture date of 1991 with a 8-pin 22mm tube.

I find the 29mm 10-pin tubes more in the mid 80's models. Just stay away from any TV that is Made in Korea or "of Korean componets" I find they have a 11 pin tube.
 
The way I figure it out in-shop is to keep a cheapo led pocket flashlight handy. Try to look through the vents in the back to see the sticker on the tube.

If the tube # begins with A48 or 19 thats an almost sure-fire compatibility with all the older monitors. It doesn't guarantee thick/thin neck but sometimes you can see that through the vents too. If it begins with A52 or 20 chances are thats a 20in tube and while it may still be compatible with most chassis - they don't fit the arcade monitor frames in most cases. There's been others that had no problem so I'm assuming it depends on the type of monitor or the style of the frame.

If you do pick them up - please send me the make and model #s of the tvs and what tube #s they had inside - i've been trying to keep track...

My MCAFEES anti virus advises against using this site. Why?

Thats interesting - its my personal site, and I can assure you there's no crapware to be found, nor do I serve up any ads that would have any either. It is a CMS based site maybe thats what it doesn't like. (I am an IT person).
 
Got 1 TV today, it's a 20", 90 degree deflection, 7 pin, tube# MVA51ADY00x...looks like its of no use to me.
 
Look on the tube you are trying to replace. you will see the glass raised up most likely with a 90 but i've also heard it can say 100. You have to look around for it.
 
IIRC it's embossed into the glass of the tube.

Most of them are 90°, I think.

And is 90° the right angle for an arcade monitor? I was only aware of tube size, # of pins and yoke impedance as things to look for.
