TungSol KT150 Matched Quad
TungSol KT150 is a monster power tube.
This space-alien-looking-tube can dissipate a whopping 70 watts. That means it can output twice the amount of power as a 6L6GC!
The egg shape glass is not only special and unique, the shape allows for better thermal dissipation, and drastically reduces microphonics.
KT150 is not only the most powerful output tube on the market today, but it is by far the best!
