6SN7 EH, Matched, Balanced

Matched & Balanced selected premium tubes

From EH: "High quality 6SN7s have virtually disappeared... until now. The 6SN7EH is a beautiful sounding tube, on par with RCA's red base 5692. It maintains a linear response while being able to accept a full voltage. Vintage amp users and audiophiles will be thrilled to find that a superior quality, ultra low noise replacement finally exists."
