Valve Amplification Company "Vintage" aka "V100" 100W monoblock power amp (one pair)

This pair of V100 high-end valve (tube) audio power amplifiers is from the estate of the original owner, a relative of a friend from our church choir. These monoblock amplifiers are extremely rare audio components, and deserve a brief overview of them and the company that produced them.

They were designed and produced by the Valve Amplification Company (VAC) of Sarasota, Florida. The VAC website home page greets you with: "Welcome to the official website of Valve Amplification Company, Inc., designers and manufacturers of the world's finest audio instruments since 1990" (http://www.vac-amps.com/homepage.htm). A little known fact is that this is the company chosen by Marantz to build the reissued Marantz Model 7 and 9 components for them. By then the VAC was one of the very few companies who could meet their quality requirements for manufacturing these legendary tube products.

The "VAC Vintage High Power Mk II Monophonic Power Amplifier" known as the "Vintage" or just "V100" is described as a wideband low-feedback monoblock power amplifier producing approximately 100 watts per chassis. The design is largely based on the legendary Williamson circuit, which was first published in England in 1947, and was the mainstay of the original high fidelity movement.

Significantly refined in the V100, this circuit delivers true state-of-the-art performance, not sonically bettered by the more complex designs of late. The output stage features independent cathode bias for each tube, which results in excellent sound and the most stable and maintenance free operation available anywhere.

Premium parts are employed throughout, including 14 pound 22 section bifilar-wound ultra-wideband output transformers, polypropylene and polystyrene signal capacitors, high current rectifiers, low ESR power supply, and proprietary wiring. The quality of parts and careful layout allows the use of very little feedback for high sonic purity and low distortion.

Physical Condition: As close to mint as you can get. I didn’t see any discoloration, scratches, etc. The top of one of the transformers has a very slight rub mark. That's it!

On the test bench (HP339A): They meet/exceed all their specs. I reset the bias on each output tube just to get a feel for it. They didn't really need adjusting. BTW there is a spare KT88 (new).

Listening tests: I listened to them on a wide range of material including very subtle solo female voice, jazz, big full orchestra, and rock, on both CD and vinyl. The V100's sound flawless!

Sold as-is, guaranteed not DOA.
