Alchris Audio – Booki Compact Bookshelf Speakers
Let us introduce to you our brand new TX booki, pretty much like any other small speaker I hear you say, well not quite! The Booki is designed to excel in a quality audio system where space is limited and a bookshelf is used to stand them on. Of course you could sit other small speakers on a bookshelf our sideboard, but here’s where the Booki is different.....
First Watt SIT-4 Power Amplifier
The SIT-4 is the First Watt power amplifier using the industrial grade Static Induction Transistors. It is preceded by the ground breaking SIT-1, 2, and 3 and follows their technical philosophy and construction. An important difference in the SIT-4 is the SIT device itself.
The previous three designs used Silicon Carbide to make a custom vertical power Jfet with a low impedance Drain whose character nicely emulated a power Triode tube, but directly operating at the current and voltage that would drive loudspeakers without the requirement for an output transformer.
SITs lend themselves to high quality audio performance with very simple Class A circuits with little or no dependence on other active circuit elements or negative feedback.
