[ARC5] BC-454-B Dymamotor Question

[Mark K3MSB]

I decided to refurbish the dynamotor that produced the least offensive
waveform and it's on the bench completely disassembled.

C34 Across the LV contacts -- It's a square Micamold.  Is this really a
mica cap, or a paper cap?  It tests OK up to 600V on my IT-28,  and
measures around 0.001 on both my IT-28 and digital checker.  If it's paper,
I'd probably replace with a disc on general principle.

It looks like the negative winding on the LV side was completely broken
from the terminal screw;  I'm not sure if the dynamotor would have even
worked if that was the case.  I was pretty careful disassembling the unit,
so I don't think I yanked anything too hard.  Maybe it was hanging on by a
few strands to begin with.   I'm now using only side of the crimp connector
now and I used a bit of solder;  looks OK now.

Brushes look OK,  but the top half of the HV brushes are a reddish / orange
color.  I will VERY VERY lightly sand the brushes at the contact points.

Armature looks OK.

I notice the there is nothing connected internally to the ground pin on the
base connector.
