This Fender Blues Junior valve kit contains three Sovtek 12Ax7WC’s and two Sovetek EL84M ‘s.
This is an excellent upgrade kit for a Fender Blues Junior amp
The Sovtek 12AX7WC is a higher gain valve. It is a lovely balanced tone pre-amp valve and has reputedly the lowest microphonics of any of the Russian manufactured 12AX7 types. The “W” denotes that the valve is ruggedised giving you a valve that has the endurance for combo amps.
The Sovtek EL84M is a ruggedised valve and is slightly wider than the standard EL84 . The “M” stands for miltary as it is a ruggedised long life valve. It will last 2-3 times longer than any standard EL84 and it will produce 2/3 more watts per valve. It is good for increasing headroom on 15 watt amps. You will have a bit more volume before the amp breaks up
We use our SUPERMATCH process to match the EL84’s and we supply a matched balanced 12AX7WC for the phase splitter position
You will receive a test certificate showing the matching info. Valves are made in Russia and tested to US Dept of Defense standard 133 Revision D at the factory. We also test them on our Avo testers.
The prices include VAT and 1st class UK shipment and we ship worldwide. Shipping options are available at checkout.
Your valves come with 180 day warranty.
