Budda Chakra Compressor

Here's an optical compressor I came across on FSB and hadn't seen a layout of it before. There's some question as to whether the schematic is accurate on FSB, so build with care. The original uses a rectifier array component, but I've broken that down into 4 discrete diodes (1N4148, 1N4001, etc.) since I figure more people will have those on hand than the rectifier component. Should fit nicely in a 1590B. Schematic and more info on FSB.

    1. Hello friend, you are not the only Brazilian to visit the page, so even to speed up the response process, speak in English, not Portuguese! The diodes are 1n4148!

    1. Probably. Usually the letters after the numbers are manufacturer specific.

  5. Collected. Does not work. The LED does not light up. Something is wrong in the original scheme.

    1. is the order of the diodes correct? mine's working, but I can't hear it 'compressing' and it has a slight overdrive when the gain is about 75%. Does the LED on your build light up? TIA!
