Hi guy,

I finally finished my 1176 stereo compressor.
Thanks to Gyraf, Hairball audio, Mnats and everyone who help me.

some pics :

Frequency response :

Modifications :

Change R84(1k) to 2,4K
The 1k resistor gave me this result :

The 1176 is a killer unit, no hum, a very warm and fast compressing.
I love it!

Sweet! those 1176s are hard to beat. I want to build 12 more of them!

R84 is the load resistor of the output transformer. Put 2.4k here give a better frequency response.
