Independent shopping perspective
The Korena take
Brownie is a compact voltage controller made for modern tube amplifiers. It accepts 120V, 50–60Hz power through a standard IEC AC cable and provides an AC grounded outlet for the amplifier. Lowering voltage is adjustable in one-volt steps; increases use three- or five-volt increments. Fuse options address smaller and larger amps, and the unit is rated for up to 480W / 4A. Its handwired construction and 2.8 lb format suit regular moves between home, studio and stage setups.
Strong match
Who this is for
- Keeping a tube amplifier’s voltage setting consistent when moving between venues with different outlet voltage.
- Studio and stage setups that need volt-by-volt adjustment of a modern tube amplifier.
- Transporting a smaller voltage-control unit between home practice, recording sessions and gigs.
