[Hammarlund] SP210SX

[Al Parker]

Hi Guido,
	You're right, Hammarlund was particularly silent about the specifics of 
T-7.  I've just ckd several manuals, the best I can find is that it was 
a Chicago Transformer co. Spec. no. 4212-C (special).  As a guess, I'd 
say the secondary would be in the 12-15k range, maybe higher.  Someone 
might have some Chicago Transformer catalog info, but it might not help.
	Perhaps Gary Brown, WZ1M, might have one available, he's got a lot of 
parts, try at

	Bill gates seems to raid my email address book regularly, so I can't 
give you his email.  I've been a satisfied customer several times.  He 
also rewinds transformers, so might know the specs.
73,

Al, W8UT
