I bought a pair of DBX 160XT's and want to recap and do some same modifications to it. However, the schematic from DBX is hard to read and I'm having a hard time reading it. Below I attached a link, it's 7 pages
I'd like to replace audio capacitors, replace the coupling capacitor, increase the size of the power supply capacitors, change the VCA with a THAT 2180A, and replace input and output op-amps. I'll also add power supply bypass and any phase compensation caps that are needed.
From what I can tell, the power supply capacitors are C3-C6, and the VCA is the DBX 1252 (U11). I'm pretty sure the LM353N (U1) is the input op-amp but I'm not sure what the output op-amp is (U4?). I'm not sure where the coupling capacitor is.
Here is a link to schematics from DBX:
