Hi all, my first post!! I've recently rediscovered all my old four track recordings from the 80's and 90's (yes, I'm getting on a bit!) and want to listen to them again, however, I do not have the original Tascam Porta 05 four track recorder they were recorded on - does anyone know if I could successfully play these tapes back on any cassette based 4 track recorder, or will they only really respond to being played back on another Tascam Porta 05? (they seem to be a bit rare on the UK ebay site!) Thanks in advance.
