I was wondering what the performance differences were with the change mid season in the 1931 Model 112, from the 45 output tubes to 47's. Then the following year the big 11 tube chassis made another change to the 42's for the output (model 15). Which of these three is considered the "Better" tube with best sound ?

Absolutely no one is going to reverse engineer that circuit. Even the iron core is missing.RodB — 10:37 AM
