   Remarks:

    1. Input voltage varied from 100vac to 135vac, output measured 12.36V at 320mA. Output did not change.

    2. Regulation measured from points indicated by *. Example: 500mA-1500mA, 1500mA-1850mA

    3. Some noise figures taken with 1000uF across output terminals.

   Conclusion:

    These adaptors show good long-term stability with good regulation and relatively low noise.
