I thought it would be useful to list in one place many DIY suppliers so that anyone can get quick and easy access to parts to help them build/modify/repair electrostatic ear/head speakers.
This is the 1st edition. If/when more DIY'ers provide more supply information this post (post #1) in this thread will be edited and updated to contain all latest working links.
