 Remarks:

  1. Input voltage varied from 100vac to 135vac, output did not change.

  2. Regulation measured from points indicated by *

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

  Conclusion:

  These adaptors demonstrate very good regulation over wide range of loads, with good noise figures. In some cases, the regulation  

  exceeds expectations.

  Tests done on:  Wavetek Model: DM78a DMM

                         Circuitmate 9020 20MHz 'scope Vertical amplifier shows nominal 4% error.
