Only the Mosley 303 and 404 models which were used as Studio Transmitter Links became outlawed. All of your stuff is O.K. The 303 and 404 models had a varactor tripler as the final R.F. power stage. They drove it with about 30 watts at around 315MHz and got perhaps 10 watts output at 945MHz (frequencies varied by station license of course). The problem was that with antenna icing or duplexer tuning drift the varactor output went from a single somewhat 'clean' signal to a whole bunch of unpredictable R.F. spurs which many times interfered with other broadcasters and even cell phone towers. It happened so often the units were outlawed by the FCC. Your amplifiers and such are fine. That Eventide audio delay is a 'must have' for live talk radio stations. I am not familiar with SAS stuff. My broadcast mixer experience is limited to Pacific Recorders BMX, Auditronics, Ampro, Gates and RCA. My RPU / STL / ICR experience is mostly around McMartin, Mosley, TFT, GE and Motorola. So many stations are just tearing down their studio work surfaces, laying off 'local' talent, putting up a satellite dish and rebroadcasting worthless dribble from Cumulus in Atlanta!! You do have some stuff there that would appeal to Mom and Pop stations as a source of spare parts. Give some thought to Ebay. I retired from 13 years of service aquired in 11 years (according to my pension) back around 2002. I retired from the GE locomotive factory in 2022 but still work as a ship captain and working member of International Ship Masters (ISMA).
