01

Design

Circuit design and installation by a Soviet trained technician with over 50 years of experience, right here in Adelaide, South Australia. Every individual component is tested before use to ensure it meets the required specification, with tightly matched power tubes understressed for long life and reliability. We source as much as possible from Australian manufacturers or suppliers.

02

Sound

Crystal clear high frequencies, surprisingly impactful bass and that classic sweet EL84 midrange. Able to drive even lower sensitivity speakers with authority and finesse. Try it with your speakers and let your ears be the judge, as they are the only ones that matter.
