Jon,

Thanks.

I always wondered about the 25" vs 19" voltage to the tube thing.

I also had a brilliant idea - I sent out a global mail at work asking for someone who can read Japanese - and there are 4 people here - so I will bring in the chassis on Monday and they will translate the writting - at the least I should get the brand name.

Once again, there is no difference that you need to be concerned with.  The tubes all expect the same voltages and pinout.  There are probably exceptions to the rule, but chances are that you'll never find them.

>Yup - checked Bob's page - it's not there. Not only is there no manual, but there is not one piece of English text on it. It has the 'rollbar' chassis design like the Sanyo 14" that Atari used. It also has a switch in the set of screen controls which I haven't worked out what it's for. When it is powered on (and stays on for a minute) I can flick this switch and the screen 'flatlines' - single line across the screen - like no deflection. Anyone know what this would be used for?

Ok, at least you have something to go by.. It looks like a Sanyo monitor, so send Sanyo an email asking if its theirs (include a pic of the Japanese text).  Most likely they will say its not theirs, but they might be able to give you a clue.  Also, it helps that you are in Australia.. You can probably find people that deal with Japanese gaming companies directly who might have an idea about it.
