Vacuum woes on HP Scitex Fb750

So last week , I got the dreaded "No Service Station Current Detected" message and didn't hear the tell tale "whoosh" sound of the vacuum when the machine was purging. I have replaced the vacuum on our FB700 and this FB750 before and had no issues , they were under warranty and I got the part shipped and installed , easy. However , now they are not under warranty so I got...creative? dumb? I dunno , I saw a thread on here about a guy who ordered a step down converter box from 220v to 110v , a plug adapter and a regular 110v 1.5 gal shop vac and installed it and according to his post it worked. He was using an fb500 so I figured it should work with my fb750 as most of the parts are the same or similar. However .....when I hooked up everything and went to purge , it threw the breaker and scared me to absolute death because I thought I fried the whole unit. Has anyone had any luck doing anything like this? I'm thinking I just have to bite the bullet and buy the $600 replacement vac and move on. I know I can still print (kind of) with excessive cleaning but I have had it smear ink across jobs due to the heads being dirty and don't like that route. Any thoughts or suggestions are welcome.

we had the exact same issue and I tried the stepdown voltage unit from our HP4500 and it fried one of my boards! Yikes!!! had to get my friend who works at a local college in the electronics dept to come and fix the board. My advice... get the proper part and save some headaches. lol
