Re: Accuphase T-105 FM tuner schematic download? I remember the Sansui AU-999 with some fondness.
I myself have an Akai GX747dbx that I purchased from Japanese Stereo Mukashya in April 1984. It's still like new and works like new. One of the best decks Akai built.
Problem now with Akai servicing is lack of parts. The company went bust in 1999 with some bookkeeping skullduggery making $3M disappear. Some Singapore-based holding company bought them, but I see no focus on vintage gear. Mostly modern synths and televisions.
The GX77 is a somewhat shakey design. It's obviously a consumer deck built for light use. The mechanisms are crammed tightly together, with multiple layers of chassis, which makes for a service nightmare. I'm almost done with it, as I'm in the reliability testing phase to see if anything breaks, before I put the panels on and tell the customer it's ready.
