ok, done that. Now its a little more like really loud white noise than a squeal, but still there. Components were all tested other than the IC's. I don't know how to test them. I can try swapping them out?

Ok I'll give it a go. I've actually never done them below the PCB before, don't know why I decided to do that, just thought it would be neat.

Just finished another build and I have plugged it in to see how it goes and it's not good! Chauffeur passes sound when not on but high pitched squeal when on. I've never experienced this before. I love some input on how to trouble shoot this one.

Ok, switches have continuity so they aren't the problem, when I get a bit of time I will learn how to use the audio probe properly. Hopefully over the weekend

Thanks for that data sheet, awesome. I have never done a build report, didn't think my skills were up to showing off, maybe I should for this one so dumbass' like me can see what a switched jack is. Thanks again for your help. The pedal actually sounds really good too, especially when both are...

I believe I have figured it out, I have been trialling all the lugs and different jacks etc with alligator clips to save heaps of soldering. If I have the switching jack in the circuit and I plug into the input on the right and the output on the far left, which is the other sides output, the...

I think this is beyond me, i cant seem to get it working. The layout diagram shows one switched jack on the right hand side, ive tried the both of the mystery lugs and the effect functions but only the side that is plugged into still.

Thanks again, good tip

Awesome, thank you

Great info. Yes, the resistor just didn't want to come out! What happens if the Trace is broken? Does that mean I just live with the switch not working?

Ok I'll check those things, weird thing is it was fine before I changed the 3m9 resistor. I did make an audio probe recently still working out how to use it...

Ok, I'll give it a go

SO connect the tip and ground as usual then run a jumper from one of the two mystery lugs to the tip of the next jack? Is that right?

yep, two go to the sleeve, one goes to tip, what do the other two do and which one do i need to jumper to the other jack in the enclosure?

Ok, resistor replaced, phaser now phases and sounds how it should, I'm happy with that. However, when flicking the stage switch to the left, there is no sound at all. Works to the right, doesn't do anything to the left.

Ok, the only switched jacks I could get from my local electronics store are these. I actually don't know what to connect where. Nor can I seem to find info on them when I google. Please help!

Very good eyes, that is in fact a 3k9 instead of a 3m9, the mistakes are usually small and silly with this sort of thing. Won't have time to change it now, will do it tonight. 2n5457s are in and matched as closely as I have stock for. It is phasing, I expected the effect to be stronger maybe...

How embarrassing, lucky you guys are on the ball! I'll get me some switched jacks and see how we go

Will do, it quite possibly is 3k9.

I was using 2n5952s, don't think they are matched very well, I've just matched some 2n5457s as best I can, I had about 25 to choose from. I checked pin 7 of IC3 which I think is the top one (TLO22) looking at the PCB. Will get the 5457s in and take some readings.
