Technischen Daten 
Amplifier derived from the A-757 (and thus from the A-717) with even larger transformers and even more power in an oversized cabinet, successor of the A-88X, very similar to the analog section of the A-90D/A-91D. However, only introduced at the same time as the A-757 and A-656, therefore smaller knobs already made of plastic and plugged instead of screwed.
