Mix Bus Compressor from scratch

Hi Dave, the 1n4148 diode feed from c6 on the side chain output is reversed in the left or right channel.

Well spotted, it's an error on the right channel drawing, the finished circuit has them both positive going.

This project is not finished by the way, I just had a break to catch up on my "Honey do list".

Work on the timing dials is continuing and will be posted soon.

Looking forward to updates!

I am trying to match the "Ohmite" dials of the input and threshold controls, for the attack and Release switches.





I have produced the dials in MS Paint and will use some cellophane circles to give a durable finish.

Hi Dave, Been waiting on your results before ordering iron and other goodies. Does the unit work as intended? How does it track compared to chart in post #10.
Many Thanks Again

I have some time to work on it tonight, so I may have the answer later.

OK, I have finished the dials and installed the attack and release switches.



The threshold control was very free-running so I fitted a circle of antistatic foam to give it a nice resistance.



I will try to pass audio tomorrow
