Details
Purchased: 10-6-12 Repair 04-25-13: Fixed power supply, internal cleaning, new higher capacitance and voltage rating caps, new bridge rectifiers bumped way up in current capacity and voltage ratings, voltage regulators were all high current output and rock solid 5 VDC for the Digital circuits of the OB8, battery replaced with a holder so in 5 to 7 years I can change the battery myself. __NOEDITSECTION__
