I am sorry, we do not offer Yamamoto Amplifiers any more. It was nice selling those, but commercially it was not very interesting. So we decided to let go of it.
We still have a remaining stock of Yamamoto electronic parts, such as tubes sockets. Also some accesories. Click the green button above here, for PARTS => SOCKETS => YAMAMOTO
The VAIC Link is only for some support information about historic VAIC amplifiers. We still offer replacement tubes for those
The part with "Kits" offers mainly recommended projects to build yourself, but these are not ready-build kits in a box.
