EC81 6R4 Valvo true NOS/NIB, gold pins, f. Nobosound Little Bear P2, one pair

One pair (2) Valvo EC81/6R4 tubes. The tubes are absolutely new and in immaculate condition.

All tubes are tested and test with 100%+. We selected the pairs to have close values.

The EC81 is a replacement and serious upgrade for the 6C11 in the Nobosound Little Bear P2.

These tubes are made by Philips in their legendary Heerlen factory where Philips also produced the same tubes for Amperex, Mullard and Valvo.

The tubes come in original Valvo boxes. Boxes may have light storage wear and may have slightly different appearance than pictured.

These tubes are guaranteed to be new and unused from old Telco stock!
