Hi Guys
Greg, you must be older than you look
I was just going by a 20+ year old memory of an old Wireless World article I photocopied at the library, which seemed like it was hot on the heels of the tube coming out. In retrospect, it was probably more of RCA et al shedding light on the electron flow patterns within beam power tubes, focusing on the 6L6.
I was briefly enamoured with the 6V6 sound, but it was not compatible with more complex preamp tones. Randall's Line Backer series of amps used 6V6 output stages, and of course Jim Kelly used a quad in his amps. In the Kelly amps the quad tended to even out some of the 6V6 distortions resulting in a clearer tone, but still warm. Those small 9-pin tubes never appealed to me.
Yes, the "semiconductor tubes" or "vacuum jfets" are interesting. I believe they were developed towards the goal of making computers smaller and faster. At the microscopic level one could argue that everything happens in a vacuum. I'm not sure if it was a sideways development or interesting offshoot from the path that lead to quantum computers? All of it is certainly beyond the soldering skills I have
