The Akai GX260D, a recto verso reel to reel deck, this was my third own tapedeck. I was able to exchange my Philips N4510 which had more connection possibilities for synchronisation of slide projections. But in what concerns the sound quality and technical quality, this deck was far superior to the Philips N4510. I was happy with that switch in 1981. I used this recorder until it was replaced by the Akai GX630DB in 1999. I made a lot of high quality recordings with this machine.
