FBM9.9 Flat Belt Medium for Sansui D-77R
The Sansui D-770R belt size seemed right, so I ordered it for my Sansui Cassett D-77R...FYI it fit perfectly, you may want to add D-77R to your list with FBM9.9 Capstan belt. Unfortunately, the drive belt didn't fix the problem with my cassett deck...and, when I bought a used D-77R on eBay, it also turned out to not work (no sound, too fast play speed, no reverse). So, I'm back to square one with 2 non-working units. I was pleased with the fast delivery and good quality of your belt though.
