The responses so far deal with tube amps. I understood from posts here that preamps were less of a hassle and good place to enter the tube experience. The preamp tubes are subject to less stresses, run cooler, last longer, etc. So I have started with a tubed preamp and am happy with the easy of operation and the improvement of sound over solid state.
Adjusting tubes for bias and other tube hassles
OK I'm a newbie here and am thinking about jumping into tubes. (Have sent final tuition payemnt to last child's college.) Am concerned about the hassle of such things as "adjusting for bias," etc. that I've read about. Is it anything that a basically non-handy person has to worry about?
