Hi, Hans keep the information coming. Can you give more information on how you re-used the amplifier in the Avant. Can you give details or photos of how you made the connections for the power supply and the audio input? I think that there is a lot of potential mileage (kilometer-age) in what you have started, and many of us could extend the lives of our defunct but nevertheless much loved Avants.
Great thread..... keep it coming.
