[sdiy] germanium transistors

[Tom Wiltshire]

I've made a couple of Dallas Rangemaster clones using old germaniums,  
and I think I'd recommend the sockets. For both reasons Antti gave:  
You won't destroy them with heat, and they're so variable that the  
best way to get a good sound is to test a few likely candidates in  
the circuit once it's built. With a socket, this is easy.
