The 333XL INFINIUM features true Class-A/B technology with a 4 x 12AX7 front-end and 4 x 6L6 tube power stage. A masterful handcrafted, all-tube amplifier, the 333XL INFINIUM provides excellent heavy-rock tone with natural tube compression, yielding the sweet distortion and break-up you've come to love from the guitar icons who made rock n' roll history!
Technology years in the making, our INFINIUM Tube Life Multiplier Technology can extend the usable lifespan of your amplifier's expensive power tubes by up to 20 times, saving you huge money and ensuring the integrity of your tone. How? This revolutionary circuit automatically and continuously monitors the performance of each output tube, and dynamically drives it towards the target operating point, for an evenly distributed load. INFINIUM also compensates for the effects of aging, automatically adjusting current levels to keep your tubes sounding as good as new - even when AC line voltages drop below nominal levels. Similar technology has been used for decades in all-wheel drive cars, where systems modulate the power going to each wheel to improve traction. Just consider the 333XL INFINIUM as "4-wheel drive" for your guitar.
The 333XL INFINIUM takes all the guesswork out of tube replacement by illuminating an LED next to a tube that is reaching the end of its usable lifespan. And thanks to INFINIUM's Auto-Bias design, you simply replace the indicated tube - without a trip to the repair shop, saving you even more money.
Available exclusively from BUGERA, INFINIUM Tube Life Multiplier Technology is a major breakthrough in amplifier design and manufacture, providing incredible reliability for your stage performance and more consistent sound over the lifespan of your tubes. Since they are always operating at optimal levels, your output tubes perform more predictably and last much longer, thanks to BUGERA's marvelous INFINIUM Technology, saving you some serious money!
