Audio Research D-60 Solid State Amplifier
Great vintage solid state amplifier and a perfect match for an SP6, SP3, SP9 etc.
Perfect working condition and fully tested.
At this price, I’m not sure why anyone would buy a modern Chinese made unit over this piece of USA made heavy duty amp.
Beautifully made with massive transformer and caps.
The power supply caps are the size of soda cans.
