![]() I’ve also re-flowed all the solder joints. I’ve cleaned out all the channels between the strips and cleaned the board with a tooth brush and alcohol. C1 (.047U) won’t allow anything to pass, so it’s hard to say whether it’s a problem with the input or the cap…if I had to suspect one I guess it would have to be the cap, but as I said I replaced that with the same result. But as you can see I’m grabbing at straws here. Looking at the diagram the only way I see it going to the IC is input to R2 jumping to the “L” strip, going to L12 and jumped up under the IC. The testing is done on a test rig I built that is an enclosure with the off board wiring all done…I used star grounding. Any ideas? I’m no expert at troubleshooting or any of this obviously, but I would expect to hear something with the audio probe at input I think. At points beyond this I did get sound but no effect. I then started checking with my audio probe and discovered I got nothing at the input even after replacing the input wire and C1. I tried to build this and it didn’t work. Within the useful range, it seems like you get more distortion as you increase the pot, and more attack as you decrease it. A well-chosen resistor could replace the trimmer, but the value will depend on your trannies. Description: Amplify those softer notes to make it sound as louder as high notes with the Orange Squeezer Compressor. It’s probably better to use an internal 10k trimmer (to roughly set the bias) and an external 1k or 2k pot (to set the sustain), but it was already boxed up and I didn’t see an obvious place to put the trimmer. I isolated this band by adding an arrangement of resistors to the pot lugs so that the useful range (which is less than 5% of the original sweep) now spreads over the whole sweep. ![]() Useful settings are somewhere inside this band. Sorry for the confusion.īTW, according to what I read, you should find the narrow range on the sustain pot where the volume increases dramatically. It should be silent at 0 and get louder as you increase the knob. After I built it, I read up on how to set the sustain and found that your wiring is correct and I had reversed it. The Orange Squeezer compresses the dynamics of the music or of the individual notes without adversely affecting the attack of the note and without adding any significant noise or distortion to the signal. I assumed that the sustain knob controls compression so it should get quieter as you increase the knob.
