    I’m selling my small collection of GEC A2900 (a GEC special quality valve). The absolute king ECC81 / 12AT7 / E81CC / 6201 / ECC801s type tubes. The most sought after version of ECC81 tube and virtually unobtanium. Please mind some minor differences from a normal ECC81 type. They do function in every circuit meant to use ECC81 but are rated for higher standards compared to your typical ECC81 and have more gain, transconductance and draw 0.1 amp more heater current (check with your amp specs). They are a special long life >10.000 hour tube according to the original GEC datasheet (see below). These industrial specs make them drive the following stages of the amp with more authority and might explain why they are so popular for high-end audio equipement. Search this forum for rave reviews.

    These were removed from bulk packaging and are 100% NIB (production from week 18 (May) 1974, Hammersmith (Z), London, UK). They have the double mica and disc getters (see pictures). This lot is from a former UK reseller, hence the green GEC labels on every tube (in new condition). They were tested as "good" on my Eico 666 for dynamic conductance, leaks and shorts. Do note that the only real test for any tube is in the circuit it needs to function in, meaning your amp.

    If you buy 2, i’ll match a pair, if you buy four i’ll match a quad.

    As these tubes are very rare i set a limit of 4 tubes per buyer.
