Or perhaps a tube amp for everything. Whoa! Did I just say that?!
Of course tubes are great for many applications. When I was a child I built transistor amplifiers, but now as a man I must give up those childish ways. :)
The first thing that struck me about transistors is how fragile and unforgiving they were and still are. Protecting them is difficult and many protection circuits cause premature clipping into reactive loads like ESLs.
Tubes need no such protectors. RCA advertised a sweep tube that could take a 400% overload for several seconds. No transistor can do that.
The output transformer has become a particular curiosity of mine and making them better and better has been a long and exciting journey. I also went down the road of making an OTL with a built in Autoformer. It has many interesting characteristics, one of them being power bandwidth out past 100Khz and very high damping, Futterman style.
I have no fear of high voltage or the quips of those who know little about how amplifiers work.
