notlisted, Research orientated DIY repair of a pair of Acoustat1+1
I own a pair of 1+1 Acoustat since 1986 and gave me a good service till 2004.I live in India and tried quite a few electronic repair shops for help – no result. Having no knowledge in electronics I studied all parts/its functions of the interface + Biassupply carefully.
During my research I discovered a German Company who is themselves manufacturers of electrostats.The owner asked me to check the part with am Ohmmeter he had suggested – Bingo – he then send me 2 High Voltage Bias Supplies with plug in power source.
While waiting for the parts to arrive – I upgraded all of the Caps,Resistors + wires mounted them on a new motherboard - to the very moment I am enjoying my Acoustats rendering more details/soundstage/harmonics (no unwhanted panel noises) than ever before.
If any one needs well experienced tips on parts suppliers and other problems (no transformers)then drop me a line.
