I have been buying tungsol 6l6 and 6v6 tubes and have had several failures.
What's been working for you from a reliability and tone point of view?

I still gave 4 pairs of 1950 RCA 6V6s from two Hammond amps but I am reserving them for an unknown mystery amp build....it's good to daydream...:>)

For consistency—JJs. But they’re not always the best sounding tubes.

Their 6V6 is more like a 6L6 to my ear.

How soon after installation are they failing?

In my experience and I install 30-40 sets of power tubes per year, the JJ is the most robust. If you can find a set of NOS Winged C tubes buy them. They live a long time and sound a bit smoother than the JJ. The Winged C are expensive now that they are no longer made.

The bang for the buck tube is the JJ and it's what I have in all the amps I gig with. I've never had one come back at me with a premature failure. Preamp tubes yes, power no.



I have had poor luck with EH and most of the Russian reissues.

Older Sovteks are pretty good for 12A@7-series preamp tubes. Robust and good tone.

I have more than a lifetime supply of used tubes. Mostly RCA but lots of other brands. I use these used tubes in all my amps with few if any failures.
Some tubes I have may be NOS but not for sure. I have had good luck with JJ's but I prefer some good used RCA's. I usually put different brands of tubes in my amps.

It's just a guitar, not rocket science.

JJ for me too. With the exception of slight differences in volume, I think all tubes of the same type sound so close to identical that reliability and price is all I suggest people worry about when buying.

I can understand expensive NOS tubes in an amp used at home or for recording if that is what a player wants. Nobody can tell the difference on stage. Why put time on a nice old tube set when in the mix no one hears it?

Just my gut opinion, not based upon any scientific analysis, and open to rebuttal......

If you're using the amp at bedroom or quiet home practice volume, NOS versus newer versus 6L6 versus EL34 versus 6V6 versus 6550 versus whatever versus a solid state power amp........it's not going to matter. Does the tube work? Is it biased right? Good, proceed.

At louder gig volumes, or maybe using the amp at home with a power attenuator, then the differences might start to come through. But at that point, other things will also start to play more of a role in the tone spectrum. Speaker break up, your ears, etc.

There are a thousand great guitar tones. Pick one and do something with it.

So true. Find your sound and own it.
