Useful Sources of Information and Parts:
ER Audio in Australia is a great source for mylar, coatings, power supplies, input transformers and complete ESL kits. His prices are very good, and they ship promptly. Mylar is very well packed in a double mailer tube arangement. The products and service I've gotten from these guys is first class. I highly recommend them.
Roger Sanders at Innersound has been building Electrostatic Loudspeakers Since the 1970's. He has published many articles on the subject, as well as a book. If you don't own Quads, or would like something more "full range" or louder, his designs are worth looking into, and are fairly inexpensive to boot. His book is a wealth of ESL information and tips. I recommend it to anyone who is rebuilding ESL's or contemplating building a set from scratch. I don't agree with everything in the book, but overall it's a great learning tool to understand the fundamentals of ESL design. He is marketing a set of ESL's, I'll provide info here in the future. I'm sure they will be worth checking out.
