Fuzz Face Help needed

[Harris]

I'm builing a fuzz face and have built it and rebuilt with very poor results.  The latest attempt was working until I put it in the box and now I have only the faintest of sound coming from the amp.  I have removed the board from the box and STILL get the same results.  My voltages are as follows with PNP transistors that I got from small bear.

Q1:

E: 0
B: .005
C: 8.62

Q2

E: .001
B 8.62
C 8.61

Any thoughts on what's gone wrong?  Is there a webpage that gives voltages for the fuzz face?

If it worked and then it sopped working, my guess is you have a bad solder, or a bad connection somewhere.

The transistors are reading bad numbers. I would check all connections again for shortcircuits or stuff like that. In particular around Q2.

Are you taking the readings at the transistor leads?

That looks like at least a LITTLE bit of a problem........ 8.62v on Q2 base.... and .001v on Q2 emitter.

  I'd choose a schematic, I guess that would take alot of the fun out of it though..
  Battery voltage is anyones best guess probably 9v or so...am I close?

Check your soldering, wiring and grounding.
If the pedal work before you put it in the box maybe you have something touching somewhere it should't...

I've taken the board off of the floor of the box.  Re-flowed all the joints and check for continuity (both where it should be and where it should not), double checked all of the grounds, and I have found no problems.  I wonder if I have ruined one of the transistors with all of the soldering...depsite being careful and using heat sinks.  The bypass works fine, so the problem is not in the jacks.

  Sorry if my answer was smart. But indicating the exact schematic..I guess everyone else knows what it is.
  First FF could have many sockets, for 2Q's in/out caps at least, these are widely tweekable circuits and I suggest that one can determine better if tweeking helps them after having tried tweeks.
  Measure every resistor just prior to installing it.
  Doesn't hurt to test pots.
  Pinout your transistor, then double check it.
  Get some grab bag pnp's to pre-test your POS Gnd FF circuit, they might sound funny or gated, but then I know you have a FF circuit that is 'firing up' before exposing the Ge's to reverse polarity or something.
  Use a Trimpot instead of Q2 collector resistor, bias can be easily adjusted for transistors used.
  Trying more than two transistors in a FF circuit...odds are illuminates how much transistor selection changes what the FF can sound like. I'ts nice to have 5 or 6 or more to choose from, low leakage and gain ranges from say 68hfe through 200 hfe.
  Count and Examine [polarity, EBC Etc.] all connections at each node, individually, comparing each schematic node to the board connections.
  You can always start measuring resistances from here to there...say: Q2C to V+ = ~8k2, Q1C to V+ = 33k, Q2E to Q1B = 100k, and so on, also test continuity between 'everything' insure that every solder joint is connected.
