im using ggg's tycobrahe octavia circuit/pcb.  the only parts i substituted were the NOS germanium diodes from smallbear.  using 3pdt/led/dc jack set up mounted in a 125b

power supply voltage = 9.02
Voltage at the circuit board end of the red battery lead =9.02
Voltage at the circuit board end of the black battery lead =0


Q1
C =2.79
B =2.75
E =4.21

Q2
C=9.02
B=2.78
E=2.28

Q3
C=4.85
B=2.28
E=1.63




D1 & D2 = 0*(however i do get a signal when using an audio probe)

the transistors seem pretty good.  well to be honest, i was having more problems before i decided to post this.  now i seem to have everything working ok.  but do those voltages still look right, what about the diodes?
the wiring is correct, box bypasses, led lights, signal sounds good except for when its tweaked too high and starts to hiss.  the octave sounds pretty cool, and nice fuzz effect when the drive is turned up.

could there be something wrong, even though it seems to be doing what its supposed to?
also, my enclosure is kinda tight, so my board is just sitting on the bottom and i taped some little plastic baggies to the bottom of the lid to keep the solder
joints from touching the metal, anyone think this will cause problems?

hm, it stopped working then i went thru again and it seems fine now.
