Gold Lion U77 / 5AR4

Note: This tube is not suited to PrimaLuna amps.

New production made in Russia. This tube is well-built, smooth, refined, and balanced for the very best high-end audio sound. A great alternative to the typical OEM offerings. Please do not buy this thinking it's going to sound like a NOS Genalex U77... it won't. But... it's also a fraction of the price!
