Please note: I do not have the original packaging for this amplifier. However, it will be carefully packed for shipment. Read my feedback. I have shipped equipment previously and they all arrived safely. Local pickup at my business in NJ is welcome.
The following is from the VAC brochure 2004.
The VAC PA100/100 is a single chassis wide-band low-feedback stereo
amplifier conservatively rated at 100 watts per channel. The PA 100/100 is derivative of the Williamson design,which was first published in England in 1947,and was the mainstay of the original
high fidelity movement. Notable features of this circuit include a direct-coupled
input amplifier and phase splitter, resulting in low phase shift,and inherent
precise balance of the phase splitter (if properly executed) at all frequencies and
levels, resulting in excellent push-pull balance, stability, and low distortion.
The output stage is derived from the renowned PA90C, featuring individually
adjustable "fixed-bias" and partial-triode ("ultra-linear") operation.
Premium parts are employed throughout, including 14 pound 22 section bifilarwound ultra-wid;e band 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.
