About Otis Amplification

Otis Amplification is dedicated to providing high-end, custom, compact audio amplifiers with unique design and circuitry. All amps are designed and made by hand in our headquarters located in beautiful Kaua’i, HI.

Every amp is point-to-point wired one at a time on terminal strips. We look to utilize and source the best new and NOS components we can to give that old amp feel with superior reliability. Amps offer parts such as Allen Bradley resistors, American-made ceramic sockets, NOS Tung Sol tall glass 6SL7 preamp tubes and NOS 6CZ5 power tubes. Our first two models, Trudeau and Starla, have the ability to swap 6CZ5s for 6973 power tubes.
