Has anyone documented this? I've seen a few pictures of it done and the video on Youtube. There always seems to be some adapter from the 6100 neck board to the 25" tube socket. I guess my questions would be-

What's with the neckboard adapter/hack?

What tv tube would work? Does it just need to be the same neck/socket? I do assume some convergence and bowing issues.

Use the 6100 yoke?

I have a SW cockpit project that was long ago adapted the 19" 6100. Although I realize there would be a sharper picture with a 25" med res tube and Amp setup, it's not really necessary, if I can swap a 25" tube in and deal with the issues, for much less coin.

I'm going to hopefully restore the game this year, getting it working with a 19" 6100. I'd like to eventually put a 25" of some type back in there.

I have the RAM yoke rebuild kit and will have to make a new lower panel for under the marquee, which was kicked in. I'll also have to remake both access panel/doors and a couple of pieces across the top of the cabinet. Not that difficult, but waiting to really focus 100% on that one project.
 
I did try a 25" TV tube on my Starwars cab. (Transferred Yoke and rings etc)

All I got was a round picture in the centre, about 4 - 5" in diameter

Then I realized there were neck pins on the SW Rawland tube different to the TV tube, IE (missing pins on the TV tube). (Different Pinouts)

The next step is to build an adapter to get the pinouts right

That's where I'm up to on my project (Amplifone by the way)

That must explain the funky adapter I always see. So, do I understand you're wanting to use the Amplifone hv and deflection boards with a tv tube?

Yes, 25" TV tubes are a plenty, I have 3 or 4.

It's hard to get info on the TV tubes, IE pinouts, but I could cross reference it with the Sencore rejuv book maybe.

I have a 1980 sencore book, LOL - Do you know where I can get a more recent one Joey? :)

I evidently know a lot less than you do about monitor stuff, wish I could help!

Good luck.. I can do cap kits, flyback replacement, some diagnosing, following the flowcharts, but I've never done a tube swap. Just haven't gotten around to it, I suppose.

Well, I will keep this thread going if I find some pinouts any time soon :)
 
Why not use a 25" arcade monitor instead? That is what I have done for my Star Wars cockpit restore. I should be posting an update pretty soon on my progress, but I've got everything put together. Now I need to spend some time fixing the convergence at the edges.
 
Ok

I just called up Jomac, he is the Aust Guru on monitors

He read out the pinouts to me for the 23" and 25" tubes from TVs

They are identical to the Amplifone & WG6100 pinouts

(from http://www.repairfaq.org/REPAIR/F_VAtari1.html ) (Amp and WG6100)
Here is the complete pinout of the neck/tube.
  1. G3 (focus grid)
  2. not used
  3. not used
  4. not used
  5. G1 (control grid)
  6. G (green cathode)
  7. G2 (screen grid; brightness)
  8. R (red cathode)
  9. H (heater) (edit: GND / shared says Jomac)
  10. H (heater)
  11. B (blue cathode)
So I am not sure why adapters are needed, when the pinouts are the same.

I will bump this project along, now that I have this answer

Even though pinout is the same, the connector may be different...I believe I read that somewhere. That is why you need to make sure the TV tube you want to use has the same connector in a rejuvinator table as the original SW tube. Otherwise you will need to wire up a new connector to your HV PCB harness.
 
Did you use the Wells Gardner boards or Amplifone Boards for this setup ?

The 6100 yoke has a different adaptor than most 25" tubes. The B&K numbers are CR24 for the 6100 and CR23 for the majority of 25" tubes.

I looked into this a long time ago and I thought they were almost identical, enough so that you could use a CR23 rejuvenator adaptor (after removing the 6100 keying block) for a rejuvenation. The only difference, if I remember correctly, is the green and red guns were swapped (something a rejuvenator wouldn't care about).

In order to make this work mechanically the only thing I think you would need to do is adapt the 6100 neckboard to the tube configuration. I would use a dongle adaptor but I guess you could hack the 6100 neckboard as well.
 
I have no idea, but I wonder if you'd be able to take the neck socket/connector off of the TV neckboard and hack it onto the 6100 neck board.

Are you running it in MAME? I want to keep it original, except for the 25" Amplifone, but color XY monitor.

Nope, I am running a 25" "raster" arcade monitor + 6100 yoke + amplifone deflection/HV pcbs in a Star Wars cockpit. I am not the first to do this, either. If you do a search here or on the web you will see that many before I have gone down this road...

I will have to research this more, my Amplifone neck connector went straight on the 25" TV tube, I recall :)

That makes sense and I hadn't thought about it that way. May I ask what common 25" monitors work with the 6100 neck board? Thanks in advance for sharing. I've googled and searched, but just haven't seen that information. Sounds like that might be the way to go..
 
i would think that the 25" tube would have to be a med res like the orignal amp tubes? maybe i'm wrong about that!!! never thought about it but maybe resolution is just in the chasis....

Well, I would like to do what some would do - hack a WG6100 setup to a 25" tube. The 19" 6100 tube is std res, not medium res like the Amp, although that's why the Amp looks a bit better - it's sharper.
