bassfreq,

well I guess i have the v2 ! my unit was manufactured in 1996. yeah i bought mine used too. the condition is good except for that cracking sound once in a while. i've hooked mine up to a mixer using the main outs and i'm just using plain hifi speakers.

what do you mean by output expander? you mean the aux outs and digital i/o?

one thing i can't figure out is mine has spdif rca digital i/o jacks, but it seems i don't have the digital board installed! so why are the connectors there??? have you got digital i/o?

well mine gets hot after about an hour but it still works ok when its hot. don't use any fan to cool it though. well i wouldn't know about support because it is non existent here!!!
