     I can vouch for Tom's stuff having used it in Drake and 
Hallicrafters stuff.

     BTW, Sangamo made capacitors under the Black Beauty 
name for many years after the disasterous ones were made. 
The trouble causers were oil-filled. One of the problems 
(but probably not the exclusive one) was that the tube at 
one end through which the oil was added was also one of the 
leads. If the lead was overheated the seal was broken and 
the oil would leak out. Later BB caps were dry. The two can 
be told apart by the look of the leads. The oil filled ones 
have one thick stub at one end, the dry ones have thin leads 
on both ends. The late BB and Orange Drop caps, which have a 
very good reputation, were both described in the same way: a 
combination of paper and polyester dielectric. I think the 
only difference between the late ones was that BB's were 
axial lead and OD's were radial lead.
     Nonetheless, all of these are old enough to be suspect 
even if not the mid-1950's trouble makers.
