Fender Groove Tubes GT EL34 Medium Quartet Tubes

These Fender Groove Tubes GT EL34 Medium Quartet Tubes were the original power source for most high-powered British amplifier heads since the 1960s. With a power output of about 20 - 25 watts, they offer a pronounced mid - range punch, a tight low end, and a crisp top end. The tubes break up smoothly and get a bit crunchy when pushed hard. Their unique voice really stands out in a band mix as the mids cut through easily. They're like the big brother of the EL84. Features include a matched duet or quartet of E34L - S tubes in the medium power range, used in most high - powered British amplifier heads, and they're made in Slovakia.

Using these tubes is quite simple. First, make sure your amplifier is turned off and unplugged from the power source. Then, carefully insert the tubes into their designated slots in the amplifier. When you're ready to play, plug in your amplifier and turn it on. You'll notice the great sound right away. As for maintenance, keep the tubes clean and free from dust. You can use a soft, dry cloth to gently wipe them. Also, try to avoid exposing the tubes to extreme temperatures or humidity. When not in use, it's a good idea to store the amplifier in a cool, dry place. And remember, if you ever need to replace the tubes, always follow the same safety steps of turning off and unplugging the amplifier first.
