[ddstoys]

   The table top screen started to get a bit shakey so i ordered an new replacement chassis for it as i wanted it to be reliable...  New chassies arives i wired it all in and Bam the screen still shakes any ideas  or do i need a new tube now

Could be noise on the power rails. Have you got got another power supply that you can try? Is the game located near anything which could cause interference?

Check that everything is grounded and measure 100AC is correct (to the chassis).

Thank guys for the replies turned out to be the stepdown transformer being to close to the monitor moved it away as far as possible and its fixed.  Big thanks to Joey at jomac for the chassis and the back up support what a guy i never would have thought to move it
