You are definitely giving the author more credit than I did. I did briefly wonder if he might be talking about microphonics, but decided that would have been a possible issue in an analog system but would have been causght as a dead device by whatever error detection was (hopefully) used. I don't remember what vacuum tube logic circuits looked like. Are you sure they were much noisier than the transisterized circuits that replaced them?
