Yes. I own a pair of Acoustat X that match your description. My power supply went out and I took them to a local fellow who was able to examine the working twin and he replaced both power supply components. Of course, my circuit board was not damaged as the fuse saved me. If you do multiple searches on 'Acoustat' you will find referances to a couple of people who are still servicing and upgrading these amps. I misplaced my notes but the answer exists in the Audiogon Archives Discussion forums. If you find them, please post here so I can refresh my own database.
Acoustat - Can it be saved?
Has anyone out there encountered this? I have a pair of Acoustat electrostatic speakers - they are prototypes developed at Rockford Fosgate around 1990 so no model type associated. They are 6' X 2' flat panels with built in power supply. Recently one of the power supplys went down. The circuit board was badly damaged. The worst thing is after extenstive digging it appears that the capacitors and resistors used on the board are no longer made. The capacitor is .01 UF 6000 V. The resistor is 100K OHMS. It seems the only way to save it would be to locate a similar boards somewhere but it is looking doubtful. Anyone think there is a chance to outfit the panels with a more modern power supply? I hate to give up on this speaker. As a pair they have provided remarkable sound.
