[QUOTE="ATARI, post: 231492, member: 4471"] I own a Earthshaker system 11B 1989. I have a couple of questions. I want to reduce the display voltage from 100v to 91v by changing the 2 zener diodes on the p.s.u board. The problem I have is getting the 1N4763A Zener diodes unless I order from outside the U/K. I can get - 1N5377BG,DIODE, ZENER, 91V, 5W, from ebay will these be ok, or can anyone pass me any info. on where I can get the 1N4763A in the U/K. Another question, with the pinballs age are there any specific capacitors I need to change . [/QUOTE]
