    I had this pair of Mono Block M300 since 1994 and they are working great and sound radicular powerful and can sound compatible to McIntosh MC275 . The front ends were designed with Solid State operational amplifier to couple 8 pieces of 6550 Power Tube for each Mono Block. The output Transformer was designed with trifilar coils for coupling with plate, gride, and cathode, i.e., that is very similar to the original McIntosh MC275 power amplifier. For modern MC275, the output transformer is designed with only bifilar, one set of coil omitted to save cost. But they did not sound like their original MC275 anymore, very close to Solid State Power Amplifier. You can check with their schematics for the detail of their output transformers. This Audio Research M300 had the sound quality similar to original MC275 from 1960 units with 4 X RMS power output of MC275.The price in the listing is for a pair of mono block Audio Research M300 power amplifier in working condition. You can go Audio Research website to download their service manual with schematic.Because I am planning to move back to my motherland, I have to clear out all fantastic Audio amplifier collections over half a century.

    This is an amazing D300 power amp in black. It has clean and accurate sound with lots of headroom and is in perfect working condition. It was used in a small private smoke-free listening room and drive a pair of Tannoy System 12 Speakers. It was sent to ARC for a factory checkup in 2009 and was certified operational to all specifications. Includes orginal factory dual box shipping crate. The D300 both employs a distributed-capacitor approach to bulk energy storage for the main supply; this means that a number of high-quality electrolytics are linked in parallel to provide the energy reserves necessary to reproduce clean transients and dynamic peaks of accurately-recorded music. This design approach results in lower E.S.R. (a distortion characteristic of capacitors) and lower impedance (quicker delivery of power to the output stage when need ed). The D400MKII, while using larger capacitors for more total energy storage, also incorporates a second power trans- former dedicated solely to supplying the input stage of the amplifier. This approach gives both the input stage and the main supply of the amplifier tremendous dynamic headroom the capability to cleanly deliver power in the face of demanding program material and low- impedance speaker loads.
