Determining Transistor Pinout with DMM

Howdy,

I remember reading somewhere long ago, a procedure for determining the pinout of a transistor using only a DMM.

I printed the page out and now I can't find it!

Anyone remember such a page? I thought it was GEO but I couldn't find it there, nor AMZ.

I've got a handful of NOS 2n1486's and others that I might be able to use...

ok,

  A DMM with Hfe checker makes this a litttle easier.
  A transistor socket attachment [three longer leads to poke into the DMM enough to make contact reliably]...makes reading transistors with shorter leads possible.
  Just poke it in there the way you think EBC would be oriented, or any/all other ways, until you get a 'reasonable' Hfe indication....note which pins are now labeled EB and C as shown on the meters Hfe socket.
Convention creates following, following creates convention.

It probably was GEO.
maybe this:

Note that I found that page by pasting the title of your post into google --that was the first link.
Searching works.
