Philips ECC81 (12AT7) NOS NIB Platinum matched pair Tk2 Big Ring Getter 1963

Platinum Matched Pair (2 tubes) of Rare NOS NIB Philips ECC81

A precisely matched pair, carefully selected from original Philips factory boxes of 100 units.

Manufactured in 1963 at the Philips Suresnes plant in France, these ECC81 tubes bear the authentic “Tk2” type code and “F” factory mark, both clearly visible in the photos.

These early Philips ECC81s are renowned for their open and holographic soundstage, sweet, liquid midrange, and delicate, extended highs, with excellent tonal balance and micro-resolution. Bass is tight and articulate, offering a natural musical flow that makes these tubes a true reference in their class.

An outstanding upgrade for the Western Electric 91E, and an inspired choice for revealing preamplifiers, DACs, and integrated amplifiers.
