Another my project of TubeAmp chassis. The holes on the top plate was milled on CNC router. Other is hand made.
Chassis is built by real solid beech-wood. The wood is stained swedish red and treated with transparent varnish. Legs painted dark gray.
The center transformator cover is also wooden and hand made.
Otherwise, the tube amp sound so pleasant, like the sight of objects made of wood. :)
Nice days!

Takes me back to my early days when I worked in a radio and TV repair shop in the ‘60’s. The shop I worked in did a lot of work for the doctors in Rochester Minnesota, home of the Mayo Clinic because the shop owners mother was once the governess for the original Drs. Mayo.
I remember working on custom built HIFI eguipments built by Fisher, and others, with solid wood cabinets and, of course, all tube chrome plated chassis.

I never did see a solid wood chassis and yours looks goergeous.
Tube based equipment always seed to be a little “warmer” than solid state. I was working when the transition from tube to solid state happened and I could tell the difference without any problem.

Very nicely done. It’s nicer than my amp. But I have to ask how you’re grounding those transformers without a metal top. I’m guessing the output on that big power transformer in the middle is at least 400V. Are you running individual wires back to safety ground?

Thanks for sharing and enjoy your tube tunes.

Thank you for the appreciative words!

The vacuum tube’s sound is warmer, softer and richer in portionwise. Listening the music on tubeamps is a real enjoyment.

Technical: Yes, the transformers have individual wires back to safety ground.

Good luck and nice days!
