Loved this show. I had a four track which was a model up from this I think - a Portasound 04. I got it in 1987 or 1988 and recorded a lot of music on it and pushed it to its absolute limit by bouncing tracks. In fact I still have that four track and all the cassettes so I promise herewith to dig it out from the back of the cupboard and see if it works in an upcoming HPR show. Thanks Jon, superb stuff!
