I haven’t had to replace any tube for wearing out in 15 years or so. The only tubes I had to replace were two rectifiers in the power supply of my phono stage that were wrecked by a shelf falling on them. The power supply runs two 300B’s as rectifiers.
Just how much do you spend on tubes per year on average ?
I don't mean if you have $50k tube supply in the closet, I mean the cost of tubes that you wear out and throw away.
With my VAC Avatar SE integrated, and I use only better vintage tubes, it runs about $300 so far. I buy both new and used tubes. I do have $2500 tube supply in the closet. The amp is on for at least three hours a day, often longer.
