Does anyone have a 12-14 VDC input, around 250 VDC output and around 100mA or less dynamotor they might sell? I am thinking of a DM-34 or equivalent. I want this to run ARC-5 receivers (one at a time). Any voltage-output between 180 VDC at a low and 250 VDC at a high would be acceptable. Thanks, Ken W7EKB
