[Hammarlund] Caps?

[Al Parker]

Hi Bob,
	Nice find.  I've had an SP-600 for more yrs that I can admit, and 
haven't gotten into it yet.
	The "M" might be "Micamold", in which case replace them all.  255K is 
the value, 25+00000, or 2.5 mfd (seems large), and 104k = 10+0000 or .1 
mfd IIRC.  (I might be corrected on that.)  Micamolds are not mica caps, 
and do get leaky, as bad, or worse, than BBOD's.  The URM-25 series sig. 
gens. had them, and were notoriously leaky.
73,

These caps look like very large rectangular ceramics. Larger ones are 1 1/2 inches long by 1 inch by 3/8 inch. The smaller ones are maybe not quite an inch long, 3/4 of an inch top to bottom and about 1/4 of an inch thick. There are also a couple of even smaller ones. They are all 400 volt caps and all have the M inside of a rectangle. I haven't tested them for leakage. Should I waste my time checking them or just recap?
