Hello Cory and the list.

Actually, no.  On common axial electrolytic caps, the black end (which is an 
insulating material) will be your positive lead.  It's also identified by 
the indented ring or groove near one of the ends.

The can, or body, is negative, so you will note that the negative lead is 
attached directly to it.

That's affirmative, Sarge.

Could also be a ground-loop, too.

Thanks for the kind words, Cory.  We've sold about 180 can-type caps and 
kits since February, thanks to our wonderful customers and friends.  Most 
recently we've started stocking the multi-section can-cap for the Hammarlund 
HQ-129X.  We also did our first prototype Halli SX-117.  On the Heathkit 
front, we stock DX-60, DX-100, HR-10, HW-16, SB-301, SB-303 (no cans), 
SB-310, SB-313 (no cans), and SB-401, in both complete recap kits and cans 
only.  The rest we can get on about 2 weeks notice.  We also stock many 
Drake units including the  2-A, 2-B, most R-4 variants, T-4, T-4X, most 
TR-4's and the TR-4C.

Couldn't do it without the generous technical help of many folks from this 
list.

I apologize for this shameless outburst of capitalism, but after all, Cory 
tee'd it up so perfectly, hi HI!

Tnx again es vy 73,
