Akai GX-4000D Tape deck speed sleeve
The GX-4000D speed sleeve explained and illustrated! Here are a few photos showing the infamous GX-4000D speed sleeve. This sleeve is actually 2 pieces, the sleeve itself and the screw that holds it in position. I had to clean it a little as it was difficult to pull out of its "resting post" inside the head cover. These parts allow you, when installed to change speeds on the GX from 3 3/4 to 7 1/2. Without these parts, the machine can only run on the slower speed setting. They are stored on a special post inside the head cover, when you want to change speeds it is taken off that post and installed on the guide post of the tape as shown in the photo.
