Hi,
It's re-designed CB9146 compressor.
Opened topic to Black Market.

PLEASE READ!!! On boards,D11 and D12 showed wrong! They must be reversed! See layout documents! (I have no idea why but I got PCBs like this from manufacture.)And if you use plastic,check pins!
Made with easy to find and cheap components.But you can improve it.
Normally power section caps are 1000U/35V.But i used 1000U/63V.So caps are big. ;D
And i used only TL071 and TL072 op amps.You can use NE5532 and NE5534 or other op amps.
By the way i've used 1N60 instead of OA47 in and 1N4007 instead of 1N4002.compression section.And as you can see there is no one diode in meter section.Normally there are 1N4002 and OA47.I soldered 1N4007.Can i use 1N4007 instead of OA47?Or should i use 1N60?

Sound Samples!!!
Feedback all the way down
Set Distortion all the up (I want to hear how it affects)
Ratio is 4 with all samples
