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.

2. Circuit Boards - Circuit boards are fiberglass epoxy with gold plating over a tin/nickel

barrier. This gold layer will not corrode, while the barrier plate prevents the gold from

migrating to the lower copper layer and detracting from its appearance.

3. Resistors - All are high reliability metal film 1% resistors.

4. Capacitors - All capacitors have been eliminated where possible on the basis that “no

cap is better than the best cap.” Where they are used in the active part of the circuitry,

they are high quality film caps. The only electrolytics used are in the power supply where

large numbers provide enormous filtering

capacitance for the supply.

5. Semiconductors - There are no integrated circuits (IC) to be found in this product. Very

high quality dual FETs are the only source of voltage gain and were selected for their

superb noise performance and precision matching. The remaining semiconductors are

also of very high quality, each possessing parameters ideally suited for the specific

application.

6. Potentiometers - The volume controls are conductive plastic. These pots track with little

error and are totally neutral.

7. Connectors - Coda employs a standard RCA configuration with a gold plated case.

The balanced output connectors are Neutriks from Switzerland. These are black chrome

finished with gold contacts.

8. Wire- All signal wire has been eliminated whenever possible. Where wire is used, Coda

employs silver plated copper, 141 strand, 18 gauge wire with a silicone insulation.
