@JMHardin Back in the early 90's I had the pleasure to use one in Nashville @ Reflections Studio. It had come out of the old Capitol Records studio and used by Nat King Cole. Think it was a U47 but may have been a U41 (long time ago). It was a pre WWII model. Have a pic around here somewhere with it in the studio. You can't create quality like that, even today. Some kind of special sauce in the manufacturing process.
