Stat Electrostatic Headphone Energizer
The Bottlehead Stat is a zero global feedback, class A tube electrostatic headphone amplifier that features both 580V Stax Pro Bias and 230V Stax Normal (legacy) bias jacks. There is a single input, a balance control, and level control. It has a universal power transformer. Because of the high voltages present inside the chassis this product is only offered in assembled form.
No global feedback is used in this design, which provides a smooth, open sound. We have listened to Nectar Sound, Stax and Koss ES headphones and they all work as expected. To further enhance this design, each differential stage uses our Bottlehead C4S constant current source. These provide a very high impedance under the cathodes of each differential amplifier, providing very tight AC balance in each stage.
