![]() There are also some pseudo pin compatible variants, like kt77 that just give a different presentation. Generally speaking, there is too much variation within each tube type to even start a conversation about between tube types.įor instance, el34 - there are such wild variations from the cheapest Mullard reissues / JJ, amongst the Russian variants (SED, etc) to the 'old' Mullards, and then amongst even the old Mullards, say xf4 < xf3 < xf2. Balanced input pin 2+ (IEC-268).Īpproximately 0.6dB 16 OHM LOAD TO OPEN CIRCUIT (Damping factor approximately 14).ġ4dB SLEW RATE: 13 volts/microsecond RISE TIME: 2.0 microseconds.ġ05-130VAC 60Hz (210-250VAC 50Hz) 400 watts at rated output, 700 watts maximum, 260 watts at “idle”, 1 watt off.Ģ matched pair KT150 (Power output V1-4) 2 6H30 (Gain stage V5 and V6).I am the worst to comment, but will within my experiences with tubes. (Note that actual power output is dependent upon both line voltage and “condition” i.e.: if power line has high distortion, maximum power will be affected adversely, although from a listening standpoint this is not critical).Ģ.4V RMS Balanced for rated output. 1kHz total harmonic distortion typically 1% at 140 watts, below 0.04% at 1 watt. The new Audio Research REF160M breaks new ground sonically, aesthetically and operationally, and will be available in Natural (Silver) or Black finishes.ġ40 watts continuous from 20Hz to 20kHz. There is no need to check or adjust bias ever again. The Audio Research REF160M also features a proprietary auto-bias circuit that works with various tubes types, including 6550, KT88, and KT120, in addition to the supplied KT150 and works constantly to maintain precise bias of the output tubes, while also adjusting for tube wear. The result is a new benchmark in musicality in every criterion of sound quality. Incorporating these quality components is a special 4-layer circuit board that lowers the noise floor to unprecedented levels, and a design which was previously reserved for use in our preamplifiers. Those components are not only the best available, many are custom made for Audio Research. Audio Research engineers created a new audio circuit topology with the shortest signal path and the fewest components. It is understood that the best path is the shortest path. The power supply stage uses a newly developed High Energy Capacity Transformer and a hefty bulk storage-capacity network to provide extremely high current on demand for transient peaks and intense dynamics, as well as for prodigious bass depth and authority. Solid-state power regulation was chosen to provide increased efficiency, stability, and reliability. The Audio Research REF160M includes a sculpted cover with an integrated fan to cool the heat generated by the four (4) KT150 output tubes and two (2) 6H30 driver tubes. The power meter’s output-level markings illuminate via hidden LEDs, and the illumination brightness is adjustable. While this window allows you to see the output tubes, it also incorporates an innovative dual-layer construction with distinctively etched markings that create an integrated power meter. The designers at Audio Research wanted to create a new style that would complement the look of the REF6 preamp while also featuring a transparent faceplate that allows a view of the glowing KT150 vacuum tubes. ![]()
