If you got any info on this as well I would be most interested.
I don't have a schematic for the conversion board I'm afraid, but I imagine it would be fairly similar to the app note for converting the 2120 detector to the 2252.
I don't personally have any experience with the 4k channel comps, but I was under the impression the designs were fairly similar and there was some interest earlier in the thread in the 9k comp.
