ALWSR
Super Regulators
At-tunes are exclusive world-wide agents for the Andrew L Weekes designed High Performance Audio Regulator boards and modules (usually known as Super-Regulators).
The ALWSR was designed specially for DIY audio applications, and can be used as a high quality replacement for a TO220 voltage regulator, or as an improvement to a basic voltage supply. All components are easily sourced, and all bar the single op-amp are conventional through hole. To date, many hundreds have been successfully built by DIYers of varing skills and experience.
ALWSRs are available as bare PCBs, partially populated PCBs (with SM op-amp pre-fitted), or as fully built and tested modules.
The ALWSR is available in either a positive or negative voltage version, and can be configured to give output voltages ranging from 3 to 30 Volts DC. For correct operation, an input voltage at least 5V greater than the desired output voltage is required (or 2.5V greater if the tracking pre-regulator is not used).

ORDERING
To order ALWSRs please email us with your requirements. Payment may be made by PayPal, or for UK residents by Bank Transfer or cheque.
Note: For bare PCBs you should specify positive or negative voltage, for PCBs with op-amp fitted, specify 3-8V or >8V and positive or negative, and for fully built and tested modules you should specify the exact voltage required.
Fully built modules generally require 1-2 weeks to complete.
