Check my pathetic excuse for a web page, at http://www.seanet.com/~costello.
I just scanned in the sheet from the Moog Modular Manual, about matching Vbe
on transistors.  It has a few transistor checking circuits, directions, etc.
The page also contains the EMS-Style Diode Ladder filter that has been the
subject of discussion recently.  (BTW, any tips on construction of this
filter would be appreciated - I'd love to post them along with the schematic.)

Someday I'll put more up on the page, I swear.
