Purchased it 5 years ago in a G/W store and found it to be in perfect working condition. I also acquired a Revox B77 at the same time and compared them using several pre-recorded tapes. The first was Tchaikovsky's Sym. No 6 recorded with 4 track Tandberg duplicating heads by SMS. The quality of the recording was excellent and the playback on the Akai GX 636 was far superior to that obtained from the Revox. I then tried a Barclay-Crocker recorded tape of Schubert's 7th Sym with similar results. I don't know if the bias was off on the Revox but given the better tape handling capabilities of the Akai as well as the auto-reverse I felt that the Akai was the keeper.
I still play the Akai with the select number of pre-recorded tapes I have in my collection. Naturally, since my tape collection is dwarfed by the approximately 10K records I end up with far more hours of vinyl playtime. The Akai is going strong and I hope to continue to enjoy it for many more years.

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!

Akai GX636 Service Manual

After signing up today I downloaded the service manuals for Akai GX-656D and Akai GX-636 reel to reel decks. These are the best downloaded manuals I've seen. Thanks to those who put them up. And to this site for making them avaiable.
