Four different quads in about eight years: two Svet 88s, one EI TII, one "Golden Tube" that came with my used amp. One of those Chinese rebadged Golden Tubes would not hold bias soon after I got the amp. The rest of my tubes just slowly lost their frequecy extremes but still held biased and played reliably.
