AUDIO RESEARCH SP8 VALVE PREAMPLIFIER This does power up but it emit’s a buzz through the speakers on both channels. I’m pretty sure the valve’s are in the wrong place as they don’t heat up. Also the chassis shorting pin is missing this won’t help with the buzzing. This did work a long time ago but has sat in storage for years now. Also the top lid is missing I have looked but can’t find it unfortunately. It’s in decent condition apart from what looks like glue on the front panel. Please see pictures for condition.

Audio Research VT80 Power Amplifier, Manufactured 2017, One Owner. Taken in on trade for an entirely new system by the dealer that sold it to owner originally. Manufacturers description: The VT80 is the much-anticipated amplifier that finally allows the Foundation series to be shown as a complete system. Combining an enticing new esthetic with worry-free operation and great audio performance, the VT80 is a vacuum-tube amplifier that will open doors to a new customer base.At the heart of the VT80 are two important new features that have never been offered before by Audio Research. The first is a proprietary auto-bias circuit developed entirely in-house by our engineering department. Simply drop in the tubes and the VT80 will adjust bias for each output tube. The circuit automatically adjusts for tube wear or fluctuations in the power in real time. It will also work for different types of output tubes, including 6550, KT88, KT90, KT120 or KT150. The adjustment range is wide, but matched tubes from Audio Research still provide the highest performance. Finally, an auto-bias circuit that works in real time and does not compromise performance! The second new feature includes fusing of each output tube. In case of a fault condition in a tube, an easily replaceable fuse will blow, not a resistor. This is what we mean by worry-free operation. With the beautiful new look, the flexible connection options, and the great new features, thrilling audio performance remains our primary goal and the foundation upon which we were built. Designed as part of the Foundation series, the core of the VT80 is adapted from the Reference 75, including the same power and output transformers, similar circuit topology, and many of the same parts. The 75 watt-per-channel VT80 offers striking dynamics, powerful bass, and natural clarity combined with a very holographic presentation. The result is sonically breathtaking and provides a new reference in its price range. TYPE Tube stereo amplifier INTRODUCED 2016 OPTIONS - MSRP (US NEW RETAIL) VT80: $8,000 Local pickup or delivery to within 2 hours of Newark, DE may be arranged. Shipping to USA only unless purchased through eBay’s International Shipping Program. Includes: Original box and packaging.
