Hello, can you help me to know the specs of the input attenuator in the Universal audio 175 Compressor?
Can I replace it with a double 10k potentiometers?
Thank you!

If you're not concerned about the variation of input impedance, you could replace the balanced attenuator with a dual pot. In order to provide the input xfmr with a low enough source impedance, the pot should be 2x 2.2k. 2x10k should work somewhat, though, with the risk of altered noise and frequency response performance..
