Looking for Great Sounding ECC81 Valves For Your Amplifier?

Our replacement valve ECC81 (also known as a 12AT7 or a CV4024) valve for guitar amplifiers enables you to restore the original sound and power of your amp. Just like your guitar strings, your valves start to wear from the moment you start playing. Over time you will lose tone, power and sparkle.
