One of my power packs is a MRC TECH II Railmaster 2400. It is old, but still performs flawlessly. There is something rattling around inside the case that is really bugging me. I tried to unfasten the case halves to eliminate the rattler, but I don't seem to have the right screwdriver to open the case. An email to MRC was returned from one of their techs that said the fastener was a "security" screw. No other data provided.
Has anyone been able to unfasten the case halves of one of these power packs ? What did you use?
Any and all replies are much appreciated.
