I attempted to trade in my TASCAM DA-20MkII DAT machine for a 688 MIDIStudio today only to find out that my DA-20 didn't work. I bought the DAT back in December of 1997 with the intention of using it to mixdown and archive. After I bought the machine, a change of residence and the acquisition of a computer rendered the DA-20 of no use to me. I never plugged it in, never used it. My question is: Could the long time in storage have adversely affected the unit? It was always kept in a temperature-controlled environment except for about 4 months of storage resulting from a move back to the states from overseas. Other studio electronics have functioned well, in particular my TASCAM 488MkII and rack gear. For anyone having had a similar experience, I'd appreciate your advice. I really need to unload this thing but it looks like I'll have to have it repaired before I can get rid of it. Thanks in advance.
