Good stuff! I have spent far too much time collecting original amps, documentation, and period trade literature. Seems to be the only way to put the pieces together. At some point I started tracking various manufacturers preamp products, and continue to narrow in on exact production dates and major shifts on marketing and design. I hope to get a formal version out someday. I've started shooting response curves of the amps I have, and ideally I can eventually present sound samples of various types across history, assuming I can come up with a unified way to do the tests. And find the time, of course. I have somewhere over 60 varieties of preamps ranging from 1932 to present, with the majority pre-1965.
Best,
