Welcome to the wonderful world of vacuum tube audio!
Vacuum tube audio components can add a life to music that only the most
expensive solid-state gear can match. The Elliott Studio Arts 66-100 stereo
power amp was designed to give many years of musical satisfaction and add fun
to your listening experience. Although not inexpensive the 66-100 was designed
for the ‘real-world’ music lover and is a high value in performance and nononsense design.
The 66-100 is custom designed and hand-built. It features point-to-point circuitry,
hand matched high-temperature components and wiring, and custom wound
output and power transformers. For longevity there’s an internal cooling fan,
current surge suppression, line and B+ fusing and a filament pre-heat mode. The
casework is heavy gauge steel with internal dampening sheets. The AC input has
RFI filtering and surge limiting. Low overall loop feedback plus local feedback
around the output stage stabilizes the gain and lowers distortion. The output
stage runs in ‘ultralinear’ mode. The power supply is overbuilt and utilizes large
computer-grade filter capacitors and a big choke for an ultra-clean and ‘stiff’
reservoir. A bias meter and switch is built-in for convenience; you provide the
screwdriver.
Please be aware that this is a tube amp, it gets hot and has high voltage
potentials inside that can be hazardous to your health. Please refer all service to
a qualified technician; we will gladly supply full schematic documentation and
replacement parts upon request.
You are qualified to replace the tubes and fuses and set the bias. Please
carefully follow the procedures outlined below so you don’t waste an expensive
set of output tubes.
Now a little primer on tube amps….
Tube amps typically sound louder, more dynamic, dimensional and transparent
than a solid-state amp of the same rated output power. Tube amps have higher
levels of distortion and don’t measure as well as solid-state, but they generally
overload more gracefully with lower-order harmonics that can give a warmer,
more forgiving sound. That’s not to say they’re soft! Tubes are lightning fast and
(depending on circuit design) aren’t slew-limited like their solid-state brethren.
You will be pleased with the amount of detail and resolution you will hear from
your recordings through the 66-100. You may find that you can listen longer and
at subjectively louder levels with tubes, as there’s less listener fatigue.
Tube amps have a higher output impedance than solid state amplifiers; though
this amp has excellent low frequency extension and control it doesn’t have the
high damping factor needed to control dual 18” bass bins. That said the 66-100
should drive your ‘real-world’ (4 to 8 ohm) speakers nicely.
