I didn’t know there was one? I asked for a couple of medium res monitors 120”.

I’m in on the extra order. Happily have a 17” monitor or two.

I thought so.
Do we have enough people to make up another pallet?

No idea, but I would guess so.

I would be up for one (or more, depending on price) 17" 15khz CRTs if there is enough interest for a bulk buy.

Would be good for scratch-builds. Also, stick it in a box and you've got a nice console / computer monitor.

I bet they would fit in some 14-inch equipped cabinets. Plus, if you're stuck for a 19" monitor, I'd rather have a slightly smaller CRT than an LCD screen...

It is a big misconception that medium resolution monitors have tubes with a finer pitch ("M" tubes). Arcade monitors almost always use TV tubes ("A" tubes) regardless of the resolutions the chassis is capable of. The 25khz k7000s have A tubes...


I believe that is true in the later med res games like system 24 stuff but Star Wars and paperboy most definitely use m48aaw00x rauland fine pitch tubes.

It's just the Amplifone that has an M tube, the K6100 doesn't. And the the K7000s can have the tube you say as well as the Zenith A48ACB24X. Even the Nanao MS9-29 which usually has a Toshiba A68 tube sometimes has a Matsush*ta M68 tube.

Yes. I have done quite a bit of reading/research on this (mostly related to vectors), the A and M prefix does not mean much in itself but different manufacturers/models do have different dot pitches, making some tubes mores suitable than others for different resolutions. Read most 15khz tubes used in arcade monitors were cheaper models with larger dot pitch, have assumed this is why my tv tube build/swaps look different.

Edit, just realised I own one the VGA versions of this monitor, certainly uses the same frame and has the Chunghwa sticker though of course the tube could be and probably is different. 

Thanks

Well, the monitor with the flat tube in the above link has the INTERVIDEO VP chassis which is 15KHz and the tube is narrow neck so it could be a Samsung 17" TV tube (Italian TV maker Mivar used for their 17" models in the same years the Samsung tube A41QFG692X001, flat/narrow neck/single focus/standard TV impedance yoke). The VP manual only lists A41EAM40X01 and A41ECV40X01 which are curved/minineck though.

They sometimes leak from various sellers but the bulk sits in some warehouse as the Intervideo bankruptcy has not been resolved yet.

For new monitor/chassis in Italy there is a better source that has all the Semio stock (very similar to Hantarex).

The low res chassis that uses the Philips minineck tube is the last version of the VP series (very common and documented). The 3117C is 31khz (possibly also 15khz) and uses a 17" dual focus tube. They were meant for videopoker machines.
Yeah that one i've got had had a focus pin broken out of the neck socket as well as some other modifications, and there's an Intervideo label on the side over the original sticker saying what yoke values it works with. I would assume then that these 3117C work with those flat tubes?

I wonder how low an offer - how low is low? Smile There also seems to be a load of pureflat 17" monitors there. I wonder what they were used in? Also looks as though they have a load of crts on their own, as well as chassis. Looking at those 17" tubes, I have a load of Polo 3 chassis that are an exact match for those. In fact, that "Circuito chassis mod 3117C" - I have one of those that's apparently been modified to work on a 29" tube if I remember correctly. It's 15khz and 31khz.

Also I wonder how they are measured for sizes?

All the world except North America measures TVs and monitor using the whole tube face not just the screen area so 20" in Europe and Asia is the same as 19" in the US. Hence those 20" monitors are the right size for the cabs you mentioned.

It's a 19" with 18" viewable screen and an M46 tube (same as a 19" PC monitor). Classic arcade monitors are 20" with 19" viewable screen and A48 tubes.
