Interesting germanium to silicon guide page

[idy]

http://www.hawestv.com/transistorize/germanium1.htm

has a nice page, ostensibly how one might go about changing a circuit or piece of kit from Ge to Si. How the biasing has to change, even some ball park figures for those changes.

So hfe is current gain... or

Hybrid parameter forward current gain...

The page refers to current gain:

Current gain. The rule of thumb is that silicon devices develop ten times the current gain of germanium devices. (This statement is only true of small-signal devices.)

 I can remember finding that a few years back. I think it's one of those websites which don't really pop up on Google searches.

on that page, there is a green top hat transistor, how and where can i get one? i love how it looks, and through the magic of confirmation bias, it will sound better as well.

hmm, i might start re-packaging normal transistors for the mojo a cool package brings
