I am offering a super-rare Genalex Golden Lion EF86/Z729 vacuum tube. This tube comes from my private reserve. It was purchased many years ago as brand new and factory boxed. It has been opened and used for approximately 250 hours only. The expected lifespan of this tube is around 10,000 hours.

This is the rarest and best version of the Genalex EF86 /Z729, featuring long plates and a D-getter. It offers fabulous sound quality and easily outperforms the famous Telefunken EF806S.

The tube will be properly packed to ensure safe delivery.
