Can anyone identify this Chassis, WARNING ANCIENT MONITOR

[epicfatigue]

Hey Everyone,

Calling out for alittle help, i am chasing a schematic for this monitor chassis.
I have just started a new project its a restoration on an old old original first bar-top Space invaders machine!

The monitor works fine, but i would like to clean it up and get a schematic for it for future repairs as i will need them i am sure!

I will get some photos soon as its a big job just to take this out of the machine and will be doing it maybe tomorrow but seening i could see the model number i thought i was ask anyways.



The monitor has this.

Picture Monitor
MODEL GM-140GWS SER NO. 57745
AC    100V 50/60Hz      30W
TOEI MUSEN CO.,LTD.

Its a 13 inch Black and White CRT

This is what the Machine looks like restored
You may be saying but thats a color monitor, but this monitor actually has strips of colored cellophane across it !!!! 




Update Pics not very good, need to discharge and take lots of wiring notes before i dissemble.

Hey Thanks ED,

i went to their website but i couldn't find this model listed anywhere.
Do you know any good starting places to locate this manual.

Looks similar to a Matsushita. Not sure if they made b/w monitors though.

It's a Toei GM-140 and Bob Roberts has a capkit for it.

Hey thanks for that, but it appears to be for a 19inch color monitor, they broad layout is very different with and all the parts appear to be different.
