Hi Folks,

I am sitting up a BC-191 with a BC-312 and I have a BD-77A  12 v dynamotor
to run the BC-191.
It is rated at 12VDC at 40 amps for 1000VDC at .350 Ma.output.  My problem
is that it is missing the Brushes for the 12 VDC side of the dynamotor.
Does anyone have a set of brushes or info or ideas where to find a set of
them for this dynamotor.
Any help would be great!
Thanks
Mike W7NPA
