Welcome to Min's Tube Audio Lab! I custom build tube power amps and preamps. My goal is to provide quality products that hold on their own against more expensive tube gears that are commercially available. Tube Audio Lab amps are treasured by many worldwide for their sonic excellence, fidelity, quality, and reliability backed by personal customer service. If you’re visiting just to get a glimpse of what custom made amps are all about, please take time to check out my portfolio and feedback. If you are interested in having any of these amps made for you, please feel free to contact me. I can also build amps using your favorite schematics (have to be tried and tested). Thank you and happy listening! ~Min
