CA3083 are no problem, I can still get them way cheaper than any THAT array.
Looking at the THAT 2252 and THATs product politics I'm not sure how long the arrays will be available ...
Jakob, attached a foto of the dbx replacement. Never have seen any without, and even found some PCB overlays for the 902 with the substitute PCB drawn on top of the 146221.
However, looks like there have been many different revisions, even with 1252 and 1253 ICs.
