Tubes /// JJ ECC99 Classic
The “Standard Issue”: There is nothing “ordinary” about our stock tubes. We selected the ECC99 for its outstanding tonal quality, airy highs and beefy mid-bass.
JJ Tubes are renowned for their quality, durability, and excellent sound.
The JJ’s have a 15,000 hours life expectancy. Tubes will give you ample warning before dying: you may notice that one channel plays louder, slight distortion, discoloration, or some sparking inside the tube when you turn on the amp -this is not dangerous, but their end is near. Changing a tube is about as challenging as changing a light bulb.
All our tubes are tested and gain-matched to assure left/right channel integrity.
