Disco Tube/Yoke info
This post got me to thinking...
Could a g07/4900/4600 tube be used on a Disco monitor?
The Disco tube is: Phillips #19VMRP22, 10 pin, 29mm neck
and the G07/4600/4900 are: #19VJTP22, 10 pin, 29mm neck
The Yoke OHM rating on a Disco is (red & blue, 2 ohms / green & yellow, 50 ohms) which seems more like a Nanao/Kortek/Sanyo EZ
(red & blue, 2.5 ohms / yellow & brown, 50 ohms #510WUB22, 10 pin, 29mm neck) However I do not think they could be used as a replacement.
I also know of 2 versions of the Disco/Atari/ADI monitor chasis. I am curious if they use the same tube/yoke. I would assume they do but have not seen this information posted online to be sure. (I own both versions and can dig them out and take a reading if needed) Do you have a picture of your Disco chasis?
