If I wasn't rushing off to the dentist, when I wrote the above, I would have fixed it sooner.
When the OP mentioned "OTL preamplifiers", I was thinking of output capacitor-less preamplifiers. Most preamplifiers do not use output coupling transformers. But by far most do use capacitor-coupling. Atma MP1 and MP3 are direct-coupled, which is rare; there is no output coupling capacitor.
