Hi, I plan on building an MK2 arcade cabinet but had a few questions. First off, is the sub power supply, the piece connected to the a/c wire, a combination of parts or just one piece. Is it the powerline filter, fuse box, and isolation transformer, or is it something completely different? Also I was wondering if anyone had the dimensions for an MK2 cabinet or a universal Midway cab.. Thanks, any answers appreciated!!
