[ARC5] ARC Type 12 question

[David Ross]

Roy -

  This R-22 dynamotor has a rated output of 250V @ 85mA, as opposed to
the standard Command Set dynamotor's rating of 250VDC @ 60mA.  Both
dynamotors are sealed and both are the same size.

  The caps in this ARC Type 12 radio are all the later style, with white
(steatite?) insulator rather than the old-style mica insulator.

73 & thanks
