Need a custom audio product?
We specialize in high performance solid state and vacuum tube audio processing equipment. Our specialties include discrete component design and through-hole PC board layout. We find board auto-routing unusable for high performance audio. All our boards are hand-routed using wide traces on double-sided copper/fiberglass boards. We have years of experience with Field Effect Transistors, bipolar transistors, high voltage devices and high voltage power supplies. We work with main stream transformer houses for audio and power transformer designs.
WE PROVIDE TURNKEY SERVICES!
