Circuit suggestions: complementary GE pair?

[Ben N]

I went rummaging through the parts mess, and I came across two small bags of metal can trannies, PN1308 and PN1309 (IIRC--I'm at work now) which, it turns out are complementary NPN & PNP germaniums, min. hfe 80 per the datasheets (I haven't done any testing, as my DMM recently got fried).

So, aside from NPN and PNP variations on RM and FF, any suggestions for circuits in which using a complemntary pair (assuming I can match a pair up) would get anything extra from being GE?  I suppose a diff-amp fuzz or octave, but is there any plus in using GE in these?

  +'s
  If that's what you have, you can use them
  You may prefer the sound of the Ge's Vs. Si's.
  Use sockets to find out
  -'s
  May require diddling to get biased
  Won't tend to hold bias as well as Si
  Might be easier to find lower noise with Si's.

you'll have to play with the biasing a bit, but could turn out cool. I've messed around with it a bit and the results were promising.

Well, pete, I have 2N3904/2N3906 as well, so it's not like I am dying to build a diff-amp or such, and I happen to have Ge.  Just wondering if there is some specific circuit out there that really takes advantage. 

But I appreciate the suggestions, ad I'm game to do some experimenting.  The Bosstone idea sounds pretty cool, Andy.  How about an all-Ge Fuzzhead?

It might be cool to try that out on Escobedo's versatile Tripple Fuzz.  The original calls for 2N3906 and 2N3904.  That might create a slightly "woolier" fuzztone.
