The D300 from Audio Research is like the workhorse in their stables. Tremendously powerful with 300W per channel into 4 ohms and 160W in 8 ohms, it has more than enough “juice” to drive just about any speaker. Unfortunately, this is a completely non-working amplifier without a main transformer, therefore the unit is only for repair or for parts. Priced for a quick sale at $200.
Cosmetically, the amp looks good with minor scuff marks here and there common with use. We don’t have the original box or manual (its available online) but will securely pack it for safe shipping.
