Turbo Duo #1: This Turbo Duo had problems with any non-glass mastered discs, movies games whatever would not work. Impossible to ever play implode on it. I tried to repair it by changing out the HOP-M3 unsuccessfully, it's botched
Turbo Duo #2: This system worked flawlessly when I got it, it is now showing signs of audio cut out when playing Redbook audio. This clears up quite quickly and is inconsistant. Since I've failed to repair Turbo Duo #1 and a Turbo Express, I will probably not bother with repairing it.
