Lol. I figured about the I put, so no biggy. But I'm certain something is odd with Q3 on yours. On the one I had Q3 was flipped, take a look at the picture of the board when I got it at the top, and on the schematic the output leaves from the collector of each transistor, while the emitter goes to ground through an electrolyic cap and a resistor. If all of the transistors in yours are CBE, then Q1&Q2 would have the collector grounded, and the emitter the output to the next stage, or if they're all EBC, then Q1&Q2 are correct, and Q3 is the ones that's backwards. It seems hard for me toe explain, but take a look at the GGG schematic I posted when I got the pedal and first wanted to figure it out.V1nce69 wrote:Hi,rocket8810 wrote:Also, I just noticed, and I'm not sure if the one you have had the transistor backwards or the pinout was backward, but Q3, without a doubt should go from left to right CBE,not EBC like the rest of them. That's comparing the trace to the board I had, and the schematic for the original.
I should have the schematic done tonight, or if I get some time tomorrow during my lunch I'll finish it up.
Again, awesome work man. Thanks.
Yes I had quite a hard time at unsoldering all these parts. The 3PDT was especially difficult !! I used a solder pump, cause' IMHO it's what works best and quick so that your components won't get overheated. Resistors are quite easy to lift, capacitors soldered so close to the board not.
Regarding your last post I'm not sure of what you say because after looking closely at my board I can assure you that
on mine all three transistors are oriented the same way, i.e. C B E front left to right.
Transistors are noted as following: 2N
Maybe you can see that in one of my pictures
Thanks for drawing the schematic !
I can't imagine the time it took to get this appart to get a trace. I may have made a schematic, but without your hardwork I couldn't have do it man.
