The Bottlehead B-Team 300B System
The Reference System gets all the glory, what with those big ol' 805As staring you in the face. And you can't help to love the plucky Moreplay & SEX 4 pairing.
But what about the B-Team? Y'know... Bottlehead's legendary 300B lineup including the BeePre2 300B Preamplifier and the Kaiju 300B Amplifier kits. Well, we think they're just swell.
When you order the B-Team System, you'll get a BeePre2, a Kaiju, and two badges. Don't forget to add on their mods!
Amplifiers in the B-Team System have universal power transformers and can be used worldwide by following the wiring instructions in the manuals. Please note that international customers will need to provide their own power cords.

Upgrade your sound
BeePre2 is an impeccable preamp when built stock. But we offer a couple upgrades to make it even more incredible.
Our Bee2Quiet Stepped Attenuator upgrade replaces the base kit's potentiometers with coarse and fine attenuators stuffed with high-quality Dale resistors and adds a constant current source. Once that's installed, some builders install the Hybrid Shunt Regulator and Low Impedance Balanced Output to reduce startup thumps and convert one of the unbalanced outputs to a low impedance XLR.
Yes, you can do it!
