Re: I require information IIGS monitor

 Funny you should mention that. I am using 240v and the ceramic you are talking
about is a 6.8 ohm on my board as well as most of the other capacitors are more
then just double  than what you would find on a 110 system.

    I watched as when I switched on and it glowed through the ceramic coating and
burned out.

    Thanks for the hint.
