Our boss, Nelson, wrote a blog post. He wants us to post it. Here we are, posting it.



Hey everyone,


Our tubes are now available from Linear Tube Audio. We’ve long admired LTA and the work they do in the world of ZOTL amplifier design, and this partnership is both a vote of confidence in the work we do at Ray Tubes and the chance for us to work with a company we have profound respect for.

LTA isn’t your typical business operation. By running everything—from engineering and design to manufacturing, testing, and shipping—out of a single workshop in the suburbs of Maryland, they’ve created an environment that fosters intimacy and collaboration. The close-knit layout encourages team problem-solving and constant communication. This approach not only elevates the product quality but also strengthens the personal connection between the creators and their craft.

I’ve had the privilege of getting to know some of the key members at LTA. Mark, who founded LTA as a passion project after retiring from a successful career as an electrical engineer, cares deeply about relationships and the legacy of the ZOTL design. Nicholas controls LTA’s outward communication. If you've heard of LTA, it’s probably because of him. He’s been incredibly generous, and working with him is a joy. Behind the scenes, Jacob, the QC lead, is a major reason why LTA's products are so highly regarded. As the final gatekeeper, he ensures that every LTA tube amp meets the highest standards before it ships.

What makes this partnership special is how aligned LTA’s values are with ours at Ray Tubes. It’s clear that their commitment to technical excellence and personal relationships goes hand-in-hand with our own philosophy. We’re proud to offer our tubes as an upgrade to their amps as they continue to push boundaries with the ZOTL design. LTA is also offering Ray Tubes products with compatible amps in their lineup, which will make it easy for existing LTA customers to experience the synergy between Ray Tubes and LTA amplifiers.

If you have any questions about this partnership or the products that come from it, don’t hesitate to reach out to me at nelson@raytubes.audio. I’m always happy to chat.

Thanks for being a part of our journey.
