Matched do the same thing. It doesn't matter. They're all a little different because they're basically handmade. No filament or plate or getter is the same. They all differ a little bit. How much gas and air is sucked out of them and how much gas the getter can take out makes a difference. Tubes are complicated uncomplicated things. Manufacturers just bang them out and if you need a matched set, your dealer handles it. Did you know the longest lasting on record was in an LA studio and it lasted 10 years - 80,000 hours? Tubes that generate less heat obviously last a lot longer (12AX7).
Replaced stock McIntosh 12ax7a with gold lion ecc8
I replaced the stock tubes in my c500t which are about 2 years old with new Gold lion ECC83's and I noticed that the tubes are not lighting up hardly at all compared with the stock tube. could this be a Bias issue? The sound is different as I would expect. Bass is more round, maybee a little heavier (good for my system) Imaging is more diffuse not as spot on as I have had. They are new so some break-in is needed. Any thoughts or experiences?
