Well I'm not entirely sure which supply I was using at the time now
that I think about it. It could have been the 200mA unregulated
supply. That would make sense, as the expense of repair probably
motivated me to spend the extra few bucks on a regulated supply.

It was a long time ago and I've got no idea what really happened on an
electronic level. I just know that it died mid-gig and cost a lot to
repair. Mutterings about power spikes were heard from the repair dude.

An unregulated supply can pass a mains spike as I understand it,
proportionally. Could be wrong.

Clae.
