The primary aim is to go through several hundred old tape reels
(including, I guess, many "home audio" recordings to save any
interesting fragments for the future. So the odd (what's the
translation) multi track format where you could double up the tape to
save tape (I remember doing that in the 70s anyway with the family set
we had at home whilst recording pop music). Good output and
reliability. The reason for the trolley is that the studio is quite
full already and not a lot of space for a large bookshelf unit and the
trolley would be good to move out as required into store rather than
me doing even more back injuries and problems than before :)
