[Milsurplus] R-648/ARR-41

[Ray Fantini]

Used the holidays for finally finishing one of the low priority projects, installing a transistor inverter power supply in an ARR-41 receiver. Being that many of the AN/ARR-41 receivers that are out there have been converted by Hams for 120 volt AC operation thought people may be interested in seeing a way to convert the set back for 28 volt DC operation. I know that a couple in the group will say that only installing a Dynamotor will do but good luck finding a Eureka Williams 231-0103-000 250 volt 100 Ma unit or a stock 541-4458-005 Power Supply assembly. I have the stock dynamotor deck but decided that I do not like the noise or the vibration that it produces and always wanted to do a solid state replacement. This is why I was looking for a DC to DC inverter assembly from an ARC-51, or ARC-73 being that they both produce similar voltages and the like. If I ever want to have the added experience of the dynamotor deck again I can always take a 3/8 Black & Decker drill, tape the trigger all the way down and put that on top the radio although I did keep the original power supply assembly so that can always be returned to the radio.

Also thanks to the group members who provided the idea, source for the Ham modified power supply and the connection for ARC-51 parts.
