Heheh :lol: .. well Dave, I'm trying to keep it correct. But you know, I'm slightly dement so I trust you to watch my back and shout as soon as you see an error.

Hahah! You bet, Kernow. You are very close.

No. They are infact iron chips. I will use them to create inductor-inlays for CRTs that need convergence correction at the edges.

Kernow. I understand that you have some convergence problems with you MS9 monitor.

I wish to advise you to make a few of these induction sticks, and insert them under your yoke. You can use any metal chipping, like I did with that little box cutter knife. Chip off a piece, make a paper 'stick', tape the metal chip onto the paper stick with isolation-tape, and try it on your monitor.

But you need to take out your monitor outside of you cabinet. And you will be needing a mirror as well, to view the results in real time.

I think that your yoke has dropped these induction inlays, and there's only crumpets left. Like in Linus's MS-2930. You need to take the crumpets out and install new metal inlays. It's easy, and you've got the power, and the means to do it. You just need to take deep breath and go for it.

Come on, Kernow. I'm sure you have some neighbor who is able to help you with a trivial thing like that. Buy a few beers, maybe a couple of pizzas, and pretend to be social. It's what I would do if I'd be silly enough to own one of those Japanese-cabs. ;)

Now, I know that these cabinets are quite popular, but nevertheless they are dangerous. Today, not five hours ago, I was helping a friend of mine with one of his 29'' Nanaos, lifting it out of the cab. And man was it heavy, *and* does the frame have sharp edges! So wear gloves. Always use gloves.

And, it's technique more than raw strength. Plan it, breath, prepare, and do it. Just make sure all leads are disconnected.

Oh yes. There are complete outfits for these little rascals you know. In Japan these furry little guys have regular jobs, with uniforms and all.

Well boys, I see that you understand. There are plenty of actual workers out there who don't mind sharing our homes as long as we clean their boxes, feed them something.. , not *anything*, some are very picky about what they eat. Imagine, some are even vegetarians!?

But they do the job, and they do it well and with style. Unfortunately they don't always get the respect they deserve. Very often we blame them for all sorts of things we don't like to admit, at times we even take out our rage on these innoscent little creatures. And these guys don't even complain! That's bravery, that's real balls for you!

Back on topic here

Uncletom, what's the best brand to use in your opinion and 28" is the best yes.

Mitsubishi
Grundig
Sanyo
Sony
Lg

Did you have any problems mounting the tube also.


Anyway any info would be great.

Thanks for asking me that, Purp. Because now I'll get a chance of presenting my somewhat wild theory about the real identity of the CRTs you mention.

28'' or 29'', doesn't matter of you don't need to use it in a Sega cabinet. There's a 1-1½ cm difference in the diagonal between the 'ears'.

Mitsubishi is a very good CRT to use in almost all cases. Mitsu... had their own factory and their own little tricks of getting a good picture.

Never trust a Grundig. Because Grundig is really a Philips, Philips owned the company and made televisions under that name, and more names. It's a great CRT if it is from a good batch. (Infact I think that Grundig TVs use Philips CRTs, no?)

Sanyo, .. I'm not sure. But I'd bet that it's either Toshiba or Mitsubishi. Should also be nice to use.

Sony are exclusive snobs who won't share anything with anybody. Let them keep their pathetic technology. Even if it's flat, it's not my idea of a great CRT because you can't use it anywhere else than in a Sony TV. Clumsy and heavy. Throw it away.

Lg is a poor mans alternative to Samsung, and Lg never had their own CRT manufacturing. Thus an LG CRT is really a Samsung CRT with a simpler label. You see that they're even trying to save on their name - 'LG' is shorter and cheaper to print that 'Samsung'. Figure that. However, Samsung, and LG should be good to use.

But you mustn't forget Hitachi. A lovely piece of glass it is.

You see it is so individual, even if it's a good brand, like Philips, they can sometimes have worse batches than before, perhaps they're trying something new. Like saving on the phosphor, or the gun alloy impregnation ... That would make the CRT last for a year or two, then go red, gren, blue, yellow, magenta, .. or whatever gun dies first.

About mounting.. Where would I mount it? I had it in its original case infront of a mirror. And when I need to mount it, it will be in my own designed cabinets. Not the SEGA steel stuff. They're too cold and hostile for my taste. Infact the 28'' won't fit the Nanao original frame. There's this little gap of 1 cm, typical.

"In 1972, Grundig GmbH became Grundig AG. After this Philips began to gradually accumulate shares in the company over the years, and assumed complete control in 1993. Philips sold Grundig to a Bavarian consortium in 1998 due to unsatisfactory performance."

http://en.wikipedia.org/wiki/Grundig

Never trust a Grudig. Ok, *if* you have a well working TV, probably an expensive sod of about 40'', then good. Keep it. But if you see a 28'', or even a 29'' in your garbage. There's probably a good reason for it.

Can these tubes be used with say Sanwa 29E31S chassis for 31khz or should they strictly be 15khz.

Also testing the resistance on the yoke how would you go about doing this?
Is it a case of setting your multimeter to ohms and puttin one lead on one wire and the other lead on the other wire.

This is a great read by the way.

Cheers
