PRE-AMPLIFIERS
CPR-28  PRE-AMP RESTORATION SYSTEM
 
The Trek II ® CPR-28 is a premium product designed to provide technicians with the means to restore like-new operation to aging AO-28 pre-amps. These pre-amps were used in classic Hammond® A-100, B-3, C-3, D-100 and RT-3 organs.  The CPR-28 replaces every resistor and fixed capacitor in the pre-amp including the two multi-section can capacitors.  While not every tonewheel organ may warrant this level of restoration, the CPR-28 is provided for those organs requiring the very highest level of quality and reliability in the AO-28.

FEATURES:

  • Premium quality circuit board construction
  • Ground plane shielding over sensitive circuitry areas
  • Long life / high temperature rated electrolytic capacitors
  • Rugged standoff mounting of wirewound resistors
  • New tone and perc cutoff controls included
  • Restores tonal clarity
  • Extremely low noise floor
