Questions about tubes and gear that glows. FAQ

Re: tubes hi maintenance?

Good tubed gear doesn't break down that much. Bias every six months, replace output tubes every few years, no worse than changing a light bulb. Change filter caps every 10-15 years. Less maintenance than most cars, and I don't see a lot of people walking or riding the bus these days.

SS doesn't need as much attention, but when it goes, it really goes. Replacement transistors and circuit chips may become unobtainable after a few years, because they evolve so rapidly. But many 60-year-old tube types are still in production or available as New Old Stock.
