Looking at the possibility of doing a modern-day adaption of the DBX902 de-esser using the THAT components, much like Gyraf did with the G-SSL.
Diagrams for the 902 are on the DBX website. Seems the only really "sneaky" components are the DBX202 VCA module (easy enough to swap with the THAT218x plus some tweaks) and 2x DBX RMS modules.
I assume this RMS module could be subbed with the THAT2252 RMS detector with some tweaks to the support circuitry, but what I was really hoping for was if someone had any design notes or datasheets for the original DBX RMS module so I could compare some of the calculations used in the THAT2252 datasheet - things like the RMS timing cap, Ibias, symmetry trim, input resistor etc.
Already got some THAT2181's, and a few THAT2252's are on their way in the next week or so...
