>The YBA 1 is dual-mono design, with two separate power supplies and
>60,000µF total power supply capacitance. Only minimal negative feedback
>is used. A protection circuit is activated in the event of the output
>being shorted or because of an internal problem. Because this circuit is
>in the feedback loop, it is said to be without audible effects. The
>design is what YBA calls "class Alpha," which means that the driver stage
>is class-A but the output stage is class-A/B, an arrangement that is said
>to maintain the sonic advantages of class-A design while allowing for
>cool running and low power consumption. Unusually, there are no series
>passive components (resistors or capacitors) in the signal path, only
>transistors.  Original price $ 7,000
