Message-ID: <325@dual.UUCP> Date: Mon, 5-Mar-84 17:37:50 EST Article-I.D.: dual.325 Posted: Mon Mar 5 17:37:50 1984 Date-Received: Tue, 6-Mar-84 06:54:30 EST Distribution: net Organization: Dual Systems, Berkeley, CA Lines: 19 I picked up this interesting item at a flea market over the weekend. I have never heard of nor seen one of these before. If anyone in netland has any information please write me. Here's what I do know: Grace "Stellar Sonic" condenser tweeter (electrostatic) Model ST-14 Made by the Shinagawa Musen Co. LTD Serial #440 It has 4 panels wired in two sections. There are 4 terminals on the back, 2+ and 2-. The tweeter had no external power supply sold with it. It does not seem to want a high bias voltage and may need a transformer to run. Ring a bell anyone? Bill Kanawyer {ucbvax,amd70,ihnp4,cbosgd,decwrl,fortune}!dual!bill
