II. Material Quality

The amplier’s chassis is made from machined aluminum. All exterior metal parts are

anodized or powder coated for durability.

Printed circuit boards are berglass epoxy with gold plating over a tin/nickel barrier.

The gold layer will not corrode, while the barrier layer prevents the gold from migrating

to the lower copper layer.

All resistors are precision metal lm; 1% tolerance for 1/4-watt and 5% tolerance for

1-watt.

Capacitors have been eliminated wherever possible. No electrolytic capacitors are

used except in the power supply, where several high-capacitance electrolytics

provide outstanding ltering of the supply output.

All semiconductor devices are of very high grade. Voltage gain is accomplished with

an extremely high-quality, matched dual FET, chosen for it’s exceptionally low noise

characteristics.

All audio input and output connector contacts are gold-plated, and XLR receptacles

are manufactured by Neutrik of Switzerland. Wire is used as little as possible in the

signal path - only to connect the RCA jacks and speaker terminals to the circuit board

- and what is used is 141-strand silver-plated copper with silicone insulation.
