TYPE B CONSTANT VOLTAGE VIBRATOR REGULATOR. Origin. To allow dynamo output to be governed by the demands of the battery. Experimental Test Report. A series of Bench tests have shewn this regulator to function satisfactorily. It is the best British regulator in existence. Road Test Report. This system ran 15,000 miles on 19-EX without any failure of the regulator. (Stamped over test reports: PHANTOM II) X No. 6142 Drawing No. 6092 Part List Weight of Old Part.
