Korby Audio Dual Tube Bottle Mic - Five Capsules

The Korby Audio Dual Bottle Mic is a dual-stage tube amplifier utilizing all the benefits of the EF804s vacuum tube and premium grade audio components. The EF804s was developed as an upgrade to the original EF804 and went through a more rigorous cleaning of the raw materials and implemented a different wafer design, thus allowing for much less noise.

Each Bottle is built using Teflon coated single-stranded copper wire throughout with high-quality, two-stage circuitry. It couples paper-pure copper foil output capacitors into a BV8-style output transformer. Each one is hand-soldered with WBT silver solder.

The Bottle can be used with any KAT capsule and includes a bayonet adapter. Each capsule is handmade with ultra thin Mylar film and gold-sputtered in house.
