I’ve been playing around with the design of an optical compressor of late (something I have been curious about for some years, since I first designed more mundane ones around SSM2120’s some years ago) – after a few months I think I have something that sounds pretty good. I was quite proud of myself for figuring out what I though was a fairly novel topology – then I did some googling, found some Joe Meek schematics online and discovered … well … nothing new under the sun! You were at least 20 years ahead of me 
Anyway – thanks for being so generous with your knowledge and expertise!
