HI,
Haven't posted here in a while, but I thought I would let everyone know that I have a two part article in the November and Dec AudioXpress on my modified DIY tube electrostatic headphone amp.
It is based on a DIY circuit Stax published in the 1970s, updated with solid state current sources and a regulated power supply.
This post is made possible by the generous support of people like you and our sponsors:
