$5,511.36

Yamamoto Sound Craft of Japan is a high-end machine shop. They produce in-house whatever custom parts their audio division requires to go Kai-Zen – build big dreams in tiny steps. Wooden head shells. Cartridge parts. Precision meters. Teflon tube sockets with gold or silver-plated phosphor bronze (copper/zinc alloy) contacts. Wooden horns. Wooden tube sockets. Resin-impreganted Japanese Cherry wood panels that are hydraulically compressed, then vacuum-formed and phenol-injected to obtain Bakelite-type qualities and become hard enough to be precision CNC milled. Vintage-style tube shields. Solder lugs using the same Complite wood composite bases as the cover panels. C-core output, power and choke transformers. Ebony footers using NOS Japanese stock. Hermetically encapsulated coupling capacitors in Ebony cylinders to prevent long-term leakage. Custom speaker terminals. You get the picture. Off the shelf and over the counter are two phrases Shigeki Yamamoto does not understand.
