I often get emails and pictures from builders that have built some of the projects I’ve posted here at CascadeTubes. I like seeing all the different ways that people have taken what I provided and modified it to put their own spin on the project.
Sometimes builders follow what I’ve done closely; following layouts, schematics, and wiring diagrams I’ve published. Other times, builders take one of my designs in an entirely different direction than I did. Sometimes builders change a project for different parts or slightly different layout. Sometimes it’s to highlight some aspect of design. And sometimes it’s something to highlight their own interest or skill in a particular area. And it’s these projects that really peak my interest.
So recently an individual shared with me his version of the 6CY7 V2.0 Zebrawood amp. Now my zebrawood amplifier currently sits next to my computer desk. It’s playing some fast Jazz as I work at the computer. I look at this amplifier many times a day and in my mind, the design is inherently intertwined with the rich two tone wood cabinet and hidden electronics. But this new version of the 6CY7 design was totally different. The builder opted to take one of his silks and put a totally different look on the project. In fact, I like this presentation so much I felt I had to share it with others. Here it is.
There are many things I like about this design and presentation. Although the project is based on a PC board, the layout is spread out like a typical tube amplifier. This keeps the presentation neat and orderly. And the little details are very nice. Things like printing not only part designations on the top, but values as well, hints at the schematic underneath. Also the cutouts for transformer wires so that they can connect from the underside keeping things clean. And having the inputs, outputs, controls, and such all labeled adds a nice touch.
An amplifier like this, maybe enclosed in an acrylic case, is not only a piece of industrial art, but a serious conversation starter as well. It invites the discussion of how it came to be, how it performs, and why it is entirely unique. Everyone who sees this amplifier will know it’s special. It is a tribute to the builder and his unique skills.
This is one of the things I really like about running this website. It invites people around the world to try something different and put something of themselves into what they’ve made. And it invites them to share it with others.
So please don’t be hesitant to share what you have done. There is no design like your own.
That is seriously cool looking. A work of art.
Any information review wise on these OT’s in regards to hifi? I see them on the bay and it’s nice to see another USA product
Seriously pretty
Incredible piece of work Eric. I love it. Did you staighten the transformer and choke stickers? Mine always seem to be crooked when delivered.
Any chance of an underside view?
Thanks for putting this up Matt. Given me a ton of ideas.

I didn’t straighten any labels, just lucky I guess!
Nice write-up, thanks!
Any concerns with the pcb being able to support the weight of the transformers and chokes? Especially the power transformer.
I put standoffs on the transformer mounting bolts too, so the weight is supported.
