WAVAC Audio md - 811

This is a beautiful amp with some historical pedigree....it was owned by
Terry Cain of Cain&Cain Speakers in Walla Walla. I obtained it in
the past year ...it had power caps redone and sounds quite amazing. I am
relocating and downsizing...hence the sale. Please ask any
questions....below is information. It comes with a set of NOS 811 tubes and some other
extra tubes. I rated it 7/10 due to age, it has power caps redone recently.

“The
MD-811 Music Dandy features the classic RCA-designed 811A triode
transmitting tube, a standard in radio communications applications since
the early 1940s. The 811A features a 25-watt thoriated-tungsten
filament with tremendous reserve emission capability and a large anode
for efficient heat dissipation. It is noteworthy that the reliable 811A
is still being specified for the latest design radio equipment in 1997,
after over a half-century career of dependable service. Like other WAVAC
Audio Lab. amplifiers, the Music Dandy employs the revolutionary IITC
(Inverted Inter stage Transformer Coupling) topology. The IITC circuit
Permits music lovers to use outstanding transmitting tubes like the 811A
that will not work in familiar old-fashioned Class A circuits. Our
amplifiers unite the pure sound of single-ended directly heated triodes
with the visual beauty, bulletproof reliability, superior build quality,
and respectable power output of industrial-grade transmitting tubes. A
particular advantage of the 811A tube is easy availability and low
replacement cost. The 811 triode is still in current production because
the tube continues to be used widely used in RF applications. The low
impedance IITC driver stage used a triode wired 6Y6, another readily
available power tube, for excellent linearity and power transfer to the
grid of the 811. The high-efficiency IITC circuit provides a healthy
power output of 15 watts per channel under extremely conservative
operating condition for long, dependable service. Extremely low noise
circuitry without capacitors in the signal path preserves the dynamic
articulation of low level signals that make single ended triode
amplifiers the first choice for music enthusiasts. The low output
impedance of the amplifier ensures maximum compatibility with
contemporary 4 and 8 ohm loudspeakers. Although WAVAC Audio Lab. employ
classic vacuum tubes that inspire feelings of nostalgia. Among students
of engineering history, our attitude is strictly modern in every way. We
selected the timeless masterpieces of vacuum tube design to create
amplifiers for today's cultural lifestyle. The fresh visual appeal of
the Music Dandy complements the realistic beautiful sound it will bring
to your listening room. Typical WAVAC Audio Lab. attention to detail is
evident in fine finish and quality of materials used throughout. The
MD-811 is designed to be a solid investment in long-term listening
satisfaction. Specification Power Tube 811A Effective Power output 15
