DESIGN PHILOSOPHY 7 I. Design Philosophy and Approach The circuitry utilized in the FET PREAMPLIFIER 02b is the result of an advanced and complete design process combining innovation and proven fundamentals.
The requirements of a power supply for flawless audio reproduction are straightforward but important. The supplies in the FET PREAMPLIFIER 02b take a very direct approach to high performance. First, a top quality shielded toroid transformer with plenty of reserve current capability is used.
DESIGN PHILOSOPHY II. Parts' Quality 1. Finishes - All exterior and interior metal parts are anodized. While paint may be more impact resistant, the anodized surface is more resistant to solvents and prevents corrosion. Moreover, the anodized parts' appearance can be enhanced by either graining or bead-blasting the surface.
TECHNICAL DA T A CIRCUIT SPECIFICATIONS Frequency Response: DC to -3 dB @ 200 kHz Distortion: < .01 % from 10 Hz to 40 kHz @ 6V peak into 600 Ohms or higher, shunted by 1000 pF or less .
CARE and HANDLING 11 The interior of the unit requires no special care, due to the use of sealed controls and gold plating on contacts. If it becomes necessary to clean the exterior, a simple dusting may be all that is required. If a cleaner is necessary, any dilute commercial ammonia based product will be appropriate.
W ARRANTY 12 I. Warranty- Any failure of the FET Preamplifier 02b to operate or to meet specifications, applicable at time of manufacture, due to a manufacturing defect or component failure, will be corrected by Coda Technologies, Inc. without charge for parts, or labor for a period of ten years from date of original purchase.
