Guardian May 2016 - Power Supply Repairs


The transistor inverter is in this enclosure. It take a 24VDC input from the ship's batteries and supplies an output of 250 - 300 VDC for the valve HTs.




The above capacitors were replaced as were the two 0C29 Germanium Power transistors below.

297VDC off load is fairly healthy!
