Marty - download a manual of a game around the same period - then you can check the CPU / PSU schematics etc...

Hi Nino,

I've d/l the D.E LAH manual from IPDB but nil schematic...I found what I was looking for with Pinball-Fixers for sound board!!!

I've pulled the board out and obs that all the caps were 25v not 16v.  I've swapped out the one which I believe was correct (C30) and put new cap in.  Nil value.  Still the same with G.I interference so I guess what I've got is as good as it will get....

Next time I'm down at Marks I'll have a listen to his NIB LAH and compare & I'll try my hardest not to buy another machine!
