Oops. I thought Rich was asking about the 26Z5's.
Here s a Google link about Sigmapert (Parentheses contents mine):
(This fellow, Dr Schmid, was a member of our list some time ago, and has 
tested and written about replacements of the 3TF7 extensively.  See the 
Google search results, or this Pearls article for more:
