Up for sale is my Audio Research SD135 Solid State Power Amplifier. This amp has been the main power amp in my all balanced ARC system, having bested a host of amplifiers including the venerable Ayre VX-3 and VX-5.
The amplifier features both single ended and balanced inputs (single ended requires a shorting adapter - which is not included) and a 12v trigger input. Conservatively listed at 130w into 8ohms this amp has more than enough power to drive even demanding loads. The frequency response is specified as 0.4hz to 300khz.
The amp is in very good condition and conservatively rated at 7/10. Included are the original ARC double shipping box, manual and 20amp power cord. Here is your opportunity to pick up the last Class AB solid state amplifier ARC produced, rarely available, for a great price.
