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.
2. Circuit Board - 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". 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 connectors are Neutriks from Switzerland.
8. Wire - All signal wire has been eliminated whenever possible. Where wire is used, Coda
employs silver plated copper, 141 strand, 18 guage wire with a silicone insulation.
