PEARL BOARD CONSTRUCTION
We use precision quality parts throughout. Our fixed terminal hand crafted circuit boards are identical to the ones used in constructing the Topaz amplifier. The ease of replacing parts and the tenfold increase in lifetime durability are added benefits resulting from this board construction. These boards are held elevated from the surrounding metal chassis to avoid any capacitive coupling between components.
We import from Denmark our stepped ELMA volume controls that use 0.1% precision metal film surface mount resistors. Shallco switches are used for the selection and balance operation. All wiring for input selection uses coax from the RCA connectors to the front panel switches.
