6SN7 EH GOLD

The Gold 6SN7EH features gold plated pins for superior contact.
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."
This tube has gold pins.
