On Thursday, August 21, 2003, at 2:45pm, my wife of 34 years, Rebecca, died in my arms in an emergency room.

The last words we spoke were in perfect synchronization: "I love you with all my heart."


Hammond Preamplifier Rebuild

Filled with components, the AO28 is the "final link" before the Leslie.  After 25+ years, many of the AO28 components have outlived a reasonable life expectancy, and should be replaced.  Vibrato and percussion problems are usually traced to components in the AO28 which have failed, or are ready to fail.  Much like a mixing console, the AO28 accepts input from several Hammond circuits, mixes them, then sends them to a final output stage.

We also do certain modifications to Hammond preamps, such as adding a loop circuit, and fusing the power transformer.  ProKeys preamp modifications add convenience and reliability.  We do not alter the vintage Hammond circuitry or tone characteristics.
