with replacing the 4x 100uf 200v "black" caps in the top R corner, 
with the "zip-ties" around them first. This had cleared up the 
same "scrambled screen" problems I had a while back on an EII. It 
only took about 15-20 min. to finish the job. Eventually, I just went 
ahead and replaced all of the electrolytic capacitors on the whole 
PSU, and it has been running for a few years now, with absolutely no 
problems since! Please note that this PSU had been sitting around, 
separate from the EII itself, so it had no power going to it for a 
while. I felt much safer working on it, otherwise I would have been a 
bit nervous to start poking around on one that had been in-use. *YOU 
ALL KNOW HOW DANGEROUS PSU REPAIR CAN BE!! PLEASE BE 
AWARE/KNOWLEDGEABLE OF WHAT YOU ARE DOING IF YOU ATTEPT THIS 
YOURSELF, OR HAVE NEVER DONE THIS BEFORE* as I'm sure you want to 
live another day to play your lovely/magical EII

brought them older pieces they were not too familiar with, that just 
sat around un-touched for weeks, only to end up fixing them at home 
myself. They should have no problem re-capping a PSU if you just 
bring them the PSU only, but it will definitely cost you! I highly 
recommend contacting Ed Miller over at a place called Studio9 on 
Sunset Blvd. for anyone in the Los Angeles area. He's a bit of a 
synth guru, and would have no problem fixing the PSU on an EII (I 
believe he used to work at Roland). His prices are also extremely 
reasonable and fair, which is pretty rare these days. Hope you get it 
fixed soon!
