Alpha 500 kOhm log / Audio

Very linear working 12AX7 / ECC83 with long anode plates and spiral heating, which makes the tube less sensitive to interference from AC heating.
We recommend this tube for audio and high-end amps as well as for "modern" Fender amps with more overdrive, but also as an input tube in old Marshall JCM800s.


Note: Tubes equipped with long plates are commonly associated with a "warmer" or "richer" sound, whereas those with shorter plates tend to deliver a "tighter sound". However, tubes featuring long plates exhibit increased sensitivity to vibrations and mechanical disturbances, rendering them less ideal for critical applications.

TT Selection: Balanced
Both systems with balanced gain

• The 12AX7EH provides high gain with ultra low noise and detailed, musical tone that rivals the most desirable NOS types.

Dissimilar twin triode preamplifier tube used in vintage Ampeg amplifiers. This tube is 1/2 12AX7 and 1/2 12AU7.

Totally Tweed! The preferred OEM tube of ’50s-era Fender Tweed Champ and Deluxe amplifiers The Tungsol 6V6 has a geometry designed to safely handle the higher voltages used in guitar amps – plus heavier plate and grid materials. The result.. better mids and bottom while keeping the smooth top of the classic 6V6’s. The Tungsol 6V6 breaks up evenly from low E to high up the neck. Blues players will LOVE these tubes for the way they sing!
