Up for sale is my Hafler DH-500 Amplifier with Musical Concepts modifications. It has the PA-3E boards and the PS 200 power boards with 8 power caps. Each power cap at 12000UF for a total of 96000UF. It also has a soft recovery power switch that eliminates that initial surge [ thud ] to the speakers. The amp is in great condition and performs flawlessly. There is a slight bottom bend on the right bottom face plate. It is minor and tough to show in the photos. For Pay Pal sales, please ad appropriate fees. I changed the Cardas output connectors you see on the photos for regular ones, which sound much better. Thanks for looking!
