Siemens U273 Timing Network Mods

Beitrag von opacheco »

Hi to everyone!

I would like to share my sketch of the Bridge Diodes and Timing Network for the Siemens U273. My idea is to get any advises in order to add more control to the unit like attack control, threshold control and Ratio Control.

I believe we can add "Ratio Control" with a Double Pot in series with the Voltage Control(see the attached schematic). "The Threshold Control" will be done with a potentiometer substituting the R2 or R7 (or both!!) in the side chain preamp by installed external manual control potentiometer (see the original Siemens U273 complete schematic); I can be wrong!!......

Any comment??
