Sanders Sound Systems Magtech Power Amplifier
Eric Neff
The Sanders Sound Systems Magtech is not your ordinary Class AB amplifier.
. . . To get to the heart of it, Sanders has found that free-floating power supplies cannot maintain their proper voltage during peak music events. The drop in voltage reduces the available output power significantly and it leads to clipping reducing the quality of the amplified signal. Thus, the critical need for a fully regulated power supply. He has invented the first fully regulated power supply that generates virtually no waste heat. It is almost 100% efficient. This power supply maintains its voltage, high power, and bias level regardless of the load placed upon it. Sanders indicated he uses the latest thermal track transistors by Motorola which keeps the bias under tight control. So, he can run the amp at low bias while maintaining very low distortion levels at around 0.0001%. He also stressed that this amplifier had no protective circuitry as that leads to compromises when powering electrostatic speakers. So how do you keep from blowing up your output transistors? The answer is he uses a whole lot of powerful output transistors to reduce the strain on any single one. Looking at the picture of the amps internal circuits will show twenty transistors per channel wired in parallel spreading the stress across the group of them and lowering the impedance to around 1/100th of an Ohm which means it can deliver all the current a speaker needs regardless of frequency or impedance. . . .
