DC-DC CONVERTOR FOR THE RAF DIGITAL DISPLAY ANEROID BAROMETER TYPE M.1991 6C/2154 BY NEGRETTI AVIATION RANGE 950 - 1050 mb
The problem with these exquisitely manufactured devices is that the 60V pile to deliver HT to the DM70 magic eye indicator valve has long been discontinued rendering usage difficult if not impossible.
Fear not because now we have had a DC-DC power supply manufactured to deliver the required 60V all from a 9V PP3 battery - simpes eh!
