more shin ei build questions

[freak scene]

so i got it together and it works, BUT its pretty quiet.  2 things, i used 2n5089 transistors and i only have 100k pots, would either of these cause the quiet problem?

and for the record if you read the last post about this, in lieu of the 1m2 resistor i ended up subbing a 1m and a 2.2k in series.

None of those should be causing low output. My guess is, that one of your transistors is not biased correctly. That would mean that you have the wrong component values in there somewhere. Maybe you misread the multiplier band on the resistors, or are at nano farads on a cap that's supposed to be micro farads. Are you sure you added the 2.2K to your 1meg in series and not parallel? This pedal screams, so the only thing I can think of is what I've mentioned. There's no shame in misreading something, because the writing on caps is small, and some resistor color bands are a little iffy when they have a dark background. It would help to post the emittor, base, and collector voltages of your transistors. That tells a lot of the story right there. I've never built this on vero, but I believe Chad Hamilton has, so I believe the layout is proven. I know the schematic that's posted works, because that's what I built by.

ill post the readings tomorrow night.  i've been running around all day it being fathers day and all.

so i found a 10k resistor that was supposed to be 100k, fixed that and a little better.  but its still quiet.

here are the transistor readings.

Q1

C - 1.78
B - .60
E - 0

Q2

C - .007
B - .606
E - 0.000

i checked and rechecked all of my resistors and capacitors with my dmm and everything appears to be the right value.  i switched the transistors just in case and i ran a razor in between all of the traces to make sure there was no stray solder.

I just ran voltages on mine, and here's what I got Q1 C= 4.39V, B=.088V, E=0V. Q2 C=4.14V, B=.059V, E=0V. So, it means that with my 8.6V battery, I'm running just about half supply voltage on both collectors. I don't really know what I'm looking at on biasing voltages, but I would guess Q1 is barely workinh, and Q2 not at all. I am using OC140 germaniums in there, and I don't know how much difference there would be in individual transistor voltages. Someone else will have to chime in.

thanks.  i never really thought of using germaniums in there.
