tycho tranny bias info... confused....

[marrstians]

i've been working on my pnp tycho octavia clone and it just doesn't sound quite right yet... i was checking my voltages on my trannys and it didn't make much sense... i was reading the debuging section of geofx and wasn't sure if i should be measureing their voltages as negitaves or positives and then if it the base should be more negative or positive then the emiter... i.e. should i be doing this?...

Q1 b 2.2v
    c 2.8v
    e 2.7v
Q2 b 2.7v
    c 8.7v
    e 2.1v
Q3 b 2.1v
    c 5.1v
    e1.5v

or should they be -2.2v ect...? if i folow the geofx article how would i go about making the transistor the correct bias? just a little confused... :oops:

I used these readings as a guide when I built mine:

It looks like Q1 needs the tweaking from your voltages. I wish I knew more about biasing transistors myself, but I think the resistor on Q1s collector (going to ground) might be a place to start. I used a trimpot for that resistor.
