You guys know,...
I acquired a supposedly "perfectly working" M520 about a year ago, but when it arrived, it was less 21 2P jumper plugs, AND the power-umbilical cord. (It was already less the wood side panels, but that was clear up front, by the description). Just the mixer board & power supply, but no cable.
Needless to say, it didn't work perfectly. It didn't work at all. Tascam does not supply this cable any more, and any cable I'd consider to resurrect the M520 would be a DIY job. Not only that, but the particular connectors used were not common, and can't be found today. I've contemplated replacing the existing connectors on the PS520 and M520 to something like a standard DB-25, and then use a standard DB-25 cable for connection. That's all tentative, TBD.
If it weren't for successfully charging back this item against Visa and Paypal, I'd have been out $790. As it sits today, the M520 & PS520 is useless and is (boxed) taking up space in my garage, but didn't cost me a dime.
I've considered selling it, as is, but I won't sell the board & supply separately. I've also considered sourcing another M520,... in working condition,... as well as the obvious thing: making a power-umbilical cable, DIY.
