Hello, I guess the 2-B has to be one of my favorite receivers of all. Something that always puzzled me was the use of the 8BN8 tube. Can anyone tell me why this tube is used instead of the 6BN8? Does anyone know of someone who can repaint the 2-B front panel? Also, where is a good source for 2-B range crystals and the 4 section electrolytic? Thank you, WA5THJ.
