I just recently bought a used Mark 1 which was working great except the fact of a missing sled so I'll have to fabricate something for the car unless someone has one around (even if it's beat up).
Well, needless to say the only way to play it without the sled is with the RCA's and the barrel power connector.

So last night I was hooking up an extra power source for home so I wouldn't have to bring the power supply to and from work and it seemed to work well.
But now my Empeg is giving me problems powering up because apparently the plug I used at home was the wrong size.
Now it will only power up if I press on the plug from the side while it's inserted into the unit.

Since I'm at least the third owner of this unit I assume that I don't get any of the original warranty so I opened it up to investigate.
The problem seems to be with the negative contact in the barrel jack.
I seem to get continuity from the connection to the case full scale but only half continuity between the contact and it's solder leg. Yet if I touch the barrel of the plug to the case the unit powers up.

Can anyone on the empeg team give me an idea what to do?
I've wanted one of these since Hugo first got it started up. Now I finally got one and I killed it in a week. :((
