"Tubes have an inherent edge in bandwidth because they actually have an excessively wide (DC to RF) response which has to be limited. While a transistor has an open loop low pass corner decades lower in frequency so getting to 20KHz was the problem (all the –fb was used up just getting to 20KHz) in the beginning."
Not too out of date but in the top 10.
