[ARC5] PE-101

[mac]

Popular back in the 50's as an alternative to the more expensive  
PE-103.  Conversion details in Aug. 1952 CQ and the CQ Mobile handbook  
of the period which also details how to rewire the commutator for 6  
volt operation.  Under load puts out 610 and 325vdc with 12 volts in,  
just about right for Elmac, Harvey-Wells, etc. mobile rigs of the  
period.

Conversion involved removing the speed reducer gearbox  and coding cam  
hardware and trimming the length of the long endbell.  Made for a neat  
package.

The units still turn up on eBay with some regularity, the recent  item  
being a somewhat extreme conversion example.
