First of all, thank you very much for all of your suggestions and comments.
I usually do some preliminary checks before i start getting into voltages etc. It's going to be easier for me to link to my video then type it all out here. The info might be old news to you, or it might be useful. Either way, of the 50+ builds i've built so far, I've found 99% of the problems are solved doing these steps.
Hope it leads to a solution for you and good luck!
50+ builds? Wow! this is just my 7th build and 2nd project with failure. The 1st failure I got was caused by a bad solder. Luckily my MN3007 wasn't dead.
I'm still at work now, I'll watch it tonight.
It really, really helps people to help you if you'll post a link to the schematic you used so they don't have to go searching for it.
Sorry for that I'll do it next time. Btw, here you go http://tonepad.com/getFile.asp?id=89
Pins 2, 3 and 6 should be within millivolts of the voltage at Vb. With 9.5V at the power supply, this comes to 9.75. We see that on the output pin (6) and on pin 2. Pin 3 would be there, excepting that it's a very high impedance point. An ordinary meter can actually load this point down through the 1M resistor going to the bias voltage. This appears to be happening here; it's fine. The opamp is doing the right thing for DC.
Its a relief knowing the OpAmp is doing fine for DC. I did actually hear the audio on Pin 6 but on a low volume. I don't have an Audio probe instead I put in a wire on PIN 6 and on the other end on the output(Not sure if its the right thing to do). I'll create one of those audio probe one of these days.
Is it possible that you've confused gate and source? The gate should be at 0V, and the source at a couple of volts higher. This comes in two flavors: (1) mixing up which one you read the voltages from and (1) mixing up which pin is which on the actual part. Since JFETs commonly switch S and G pins, it's easy to confuse. Getting it wrong on the PCB will mean a non working pedal; getting it wrong on measurements confuses the process.
Good point, I may have confused the gate and the source. I'll re-check the placement and verify it again with the datasheet and the schematic diagram.
K. Apparently it was too early for me to remember the pinout. Looks like RG's got it, though I think he meant that Vb should be 4.75V.
Either of those caps could cause the problem I was mentioning, but that's less likely to be the problem given that the voltages look good.
Thanks for pointing it out. It lessens my confusion too.
