Electro Harmonix EHX 12AT7 (ECC81)
Large plate format, superior dissipation over the originals. Perfect for reverb and driver circuits.
These units are premium hand tested in my Nottinghamshire workshop to ensure consistency. You’ll receive an individual test certificate with the valve.
The 12AT7 (or ECC81 if you’re a Brit) can be used for a lower gain tone in place of the ubiquitous 12AX7. They’re commonly used as reverb drivers in Fender designs and as FX loop drivers in Orange Rockerverbs.
I’ve used these EHX valves on hundreds of amps and found them to work brilliantly. They’re made in the same Russian factory as the high end Tung Sol valves but don’t come with the high end price.
About Keld Ampworks
I run an independent repair workshop, repairing valve amplifiers and doing guitar amp repair for customers in the East Midlands and across the UK. I sell valves and guitar based electronics on ebay, only offering products that I’m confident I would use in my own amplifiers.
If you’re wondering whether this product would suit your amplifier, please just drop me a line for some advice. I’ve installed hundreds of new valves in guitar and bass amps and there’s nothing I like more than talking about it!
