Looks good, you're on the right track. You have successfully posted quotes from the book. Keep reading and eventually there is a discussion of Geoff Emerick's mic usage, George Martin's personal preferences, and how many tracks they comped to put together Hey Bulldog.
Anyway, to help the OP with his U47 website, I said that Bealtes typically used a U48 for vocals, so odds are pictures of Bealtes singing will contain a 48 instead of a 47, and I also said that Abbey Road converted their 47s to 47/48s. That is true information, and I hope it helps the OP.
Honestly, I don't even know what point you are trying to make, or really why I am even responding to you.
I would expect someone with the gull to say someone is "outright wrong," would include something in the post that give the person the ability to say so, but it's your rodeo Cowboy.
