Will a 2N2222 work in an LPB circuit?

[ProToneThinline]

Okay, I'm really sorry to ask such an idiot question, but I'm really out of practice 

Anyway, I found a bunch of 2N2222's in my junk box, and I'd like to build another boost (actually a Muff Fuzz clone).  The diargams say the transistor isn't critical, and since the 2222 is an amplifier, I thought I'd give it a try, but I don't want to fry anything in the process.

Also, I forget the lead layout.  The 22222's I have are in the plastic case with one flat side.  If the flat side is on my left, there are 3 leads vertically.  I know the center lead would be the base, but I don't rememebr the C/E arrangement.  Any help would be greatly appreciated.  Again, sorry to be an idiot, but it comes naturally to me

go to www.mouser.com, search for the 2N2222, click on it, and open the data sheet.  It will show you that flat side up, the leads are EBC, left to right.  I typically save off datasheets so I have them locally.

I don't see why you can't build a FF (or variant) with those, I have done it with 3904's, and that's practically the same transistor.  They're "garden variety".  The PNP germaniums sound less harsh, though, IMO.

jrem, thanks !!!!!  Now to see if I can make it work

The resistor values used and the biasing setup in the LPB should bias fine with all kinds of small signal NPN transistors Si and Ge.
  Now the input R is kind of low in LPBs.

  Now the input R is kind of low in LPBs. 

Gus, keeping in mind my idiot status, what will raising the resistance do?

  what will raising the resistance do? 
  Maybe Brighten up an otherwise low impedance input..
  Scale them both up [LPB has resistor bias string] and more signal gets to input, less leaked to ground and V+.
  Go to very high values at the input and you might hear the resistor noise [at the output] being introduced to the SP there.

Often you can't just raise the bias resistor values without the bias becoming more unstable.   Google Ask etc transistor bias.  There is more to it than getting the voltages you might want.

The LPB input R=
(hfe x emitter R)
in parallel with
the two input Rs in the bias string in parallel.

One can change the LPB by adding a few parts and changing a connection but then it is not a LPB.

can you throw a mosfet in a LPB circuit? 

[petemoore]

can you throw a mosfet in a LPB circuit?
  Yes, but the bias will require attention, take a look for 'Updates for Mosfet Boosters' at GEO.
  Bias a mosfet gain stage and you get a mosfet based booster...
  LPB biases most Si's.

Wouldn't a 2n2222 be a little low-gain for an LPB?  Just thinking about that; I'm sure it will sound fine, but might not be as Boostery as one would like, IMHO.
