Some of you may have noticed the 1930s-era RCA 41-B mic preamp that sold for big bucks on eBay recently. There's virtually no information out there about this dinosaur. But in my files, I happened to come across seven pages of info (including a schematic--but no part values given, unfortunately). So, it seemed natural to fire up the scanner and share it with my buddies. Enjoy!
