on my bugera amps its self bias so you dont have to buy match pairs of tubes.you can save there.I been running JJ s with no problems
You make a great point.If I am buying a new (recently produced) tube, 9 times out of 10, it'll be a JJ. IMO, JJ makes the toughest tubes and the tubes that can take the most plate voltage (and abuse). I put JJ 6v6s in my Fender Hot Rod Deville 2x12 (a 6L6 tube amp) and it was magic (also put a GWS Green Beret in for one of the Celestions). The plate voltage of the HRD is 475v (IIRC) and the JJ 6v6s can handle it. I wouldn't try that with any other brand.
If I am playing around with a low power amp, I might roll some NOS tubes and see what happens.
There are a couple good vids on YT on biasing the HR and Blues series. When I swapped the 6v6s in I had to rebias and ran them a little hot. I realize that may shorten the life of the tubes, but I am fine with that, if I get the tone that I am looking for.You make a great point.
I don't know about the rest of the Blues and HotRod series, but the Blues Junior tends to be biased very "hot" and red plating is not uncommon after tube swaps.
Unfortunately, it's also not easily biased.
