You are so right Taarzaahn!

I own all 3 different 400Ds and as far as I'm concerned there just great. Each has its own Disposition but in the end, they just make-your-day! The 'Pro' gives you the best of Two Worlds. The 'D-SS' is... (with a little extra Electronic), even able two simulate Dolby recordings. And when used as a Quad Recorder you really feel like your floating! And the ā€˜400Dā€™ is just wonderful in BOTH Directions!

Still one of the best R2R ever made and still in good shape after 42 years in use.

re: GX-400D Pro

Hi there
I have one of these in for service and much as the previous comment this one has no right hand tape tension lever. I don't think there are any left and as far as I can tell the left and the right are different. I intend to make something that will do the job from my scrap pile and see what happens else the machine is just 32kg of scrap! I think an aluminium arm with some stainless steel for the tape guide but the square boss on the end of the nylon type shaft might be a problem. I am thinking make a square boss on the top of a round stud that can be fixed into the steel sleeve by the grub screw then a little glue to hold the sleeve onto the nylon shaft. This with a little care should work. I'll let you know. I am likely to write this job up in hifi world magazine as its something that may crop up again.

Just purchased an Akai GX-400D-SS. Missing the right tension arm and speed select knob. If anyone has these parts please let me know.
