Audio Research D240 MKII Amplifier - Serviced and Powerful


Refined yet powerful solid state amp from Audio Research made right here in America.

Serviced and ready to rock and roll! We replaced the most common failure point, the protection relay, which was quite the feat. Good to go for another 20 years. And yes we used genuine ARC parts direct from the source.

Don't bother with one that hasn't been serviced as they will certainly need it after this period of time has passed. This amp is circa 1992, so 28 years as of today.

We also have a D240 if you want to run these in mono, or bi-amp. Also serviced.

In overall beautiful cosmetic condition, with no significant signs of use.

Note: RCA shorting plugs are required to enable Single Ended Operation. If you ask we'll be happy to provide a set with your purchase.
