I recently bought a tubescreamer PCB from Tonelab and soldered it together yesterday. I decided to go for Ts-9 model which requires (Ra=470ohm, Rb = 100kohm, Ca = unused) I tried to match all parts as close as possible .. some of the capacitors and resistors are a tad off (eg: 47pf instead of 51pf) but I figure it won't matter too much. All solder joints seem fine to me, no short circuits etc.
So anyway I power the circuit up and there's absolutely no output. I tried trouble shooting with the limited equipment I have (multimeter only)..
Checked all obvious things like battery, jacks, leads etc and they all seem fine. So I took a piece of wire and shorted the input and output together and I obviously got a clean signal coming through. I then followed on from the input going from 1st cap straight to output(still a signal) to 1st resistor (still a signal) but when get to transistor no output whatsoever so matter what terminal is used.
The voltmeter shows voltages at these points so I'm slightly confused. Also voltmeter shows no voltage across Ra but shows approximately 2 volts across 10k to left of it.
Can somebody please direct me in right area so I can fix this?
