I have been using this deck linked to my high end Audio Note set, it performs marvelously. Tapes I have recorded are currently astonishing customers in a vintage record shop. Most of them did not know that reel to reel machines were able to reproduce so clearly and musically.
The GX 636D performs best with NOS Maxell UD XL1 tape and when that is not around the RMG Pyral LPR 35 will do very well.

One of the best reel to reel I ever had. Sound is warm and beautiful. This machine was built to last! My GX-636 is like brand new! What I like most among his features is the auto reverse (listen and record)! One of my best reel to reel machines!

re: GX-636

A great thank you to everybody who put this site and these manuals together!
My good old trusty (GX-636) is in a bit of need for some well-deserved maintenance, and for the upcoming winter season I believe I have a new project.

All the best from Canada!
