Pungent Bzzz help (voltage readings included)

[theblueark]

Hi I'm having some trouble with the Penpen's Pungent Bzzz http://www.elixant.com/~stompbox/smfforum/index.php?topic=40917.0
There's no sound coming out of it, not even noise. Here are the voltage readings with 9V connected, no input. I built in using Dragonfly's vero layout and used the exact parts, with both Q1 and N1 being the metal can 2N2222A.

No problems with the battery, I read it to be 9V.
Voltage at the circuit board end of the red battery lead = 9V
Voltage at the circuit board end of the black battery lead = 0V

Oh and I wired the ground to the ground of the input and output jacks.



Have I missed anything?

Hope someone can help me with the debugging and thanks in advanced.

  Can you test continuity between Q1B and Q1E, both having the same readings, there's something notright.
  The Second transistor is "Upside down' I'm notsure what's up with that, or what reasonable voltages would look like.

[theblueark]

I'm getting 8 ohms across Q1B and Q1E.

The upside down transistor is a feature of this effect, as with the garage fuzz, I can't recall the exact reasoning, I'll do a search and post again.


Edit: The circuit is based on the Garage Fuzz designed by doug deeper. The 2nd transistor is a negisitor set up for use as a filter. Apparantly people have been trying different transistors and the 2N2222 or 2N2222A works best. There was a thread on the Garage Fuzz here: http://www.elixant.com/~stompbox/smfforum/index.php?topic=37639.0

Edit 2: I'm getting 8 ohms only if I place red probe on Q1E, black on Q1B. If I do it the other way around it's open. What does this mean? I tried the same for my unconnected spare 2N2222A's and they exhibit the same behaviour so I'm assuming this shouldn't be the problem.

I realised I may have the wrong value of capacitors. They have markings which I have been searching all over to see what they mean. What does 100k written on a ceremic cap mean?

[theblueark]

Success! Silly me placed a 10pF cap at the input instead of 0.1uF.

Thanks to Penpen for this gorgeously ugly sounding circuit. I'm still trying to it to clean up less early, but at least it's working now
