  • Vacuum Tube Set for Fender Hot Rod Deluxe/Hot Rod Deville, JJ 6L6GC + 12AX7

    Brand New JJ 6L6GC Matched Pair (2 tubes) This JJ 6L6GC tube is a high quality option for both guitar and home audio tube amplifiers. Big, open, articulate; these are the words that came into our head when listening to the JJ tubes. These tubes have great tone and nicely capture the “6L6 sound”, characterized by sparkling highs, warm mids, and controlled bass response. Brand New JJ 12AX7 / ECC83 Trio (3 tubes) This tube sports a different plate design than found in most 12AX7’s. When you look at them you can’t help but think that they must be rugged and good for the musician on the road. The compact plate structure does nothing to dampen their sound or dynamic response. They are well balanced. They do provide high gain without the usual noise and microphonic problems you would expect. This is great tube especially given how affordable they are.Why You Should Do Business With UsComes with original packaging from the factory, as shown in the pictureVery competitive pricesFast shippingShippingTubes will be shipped with USPS First-Class MailMost orders are shipped within 24 hoursTracking information is included for every purchaseReturn Policy Customer satisfaction is our #1 priority.

  • JJ Fender Blues Jr / Pro Jr Tube | Vox AC15 Upgrade Kit, 2x EL84, 3x 12AX7/ECC83

    Fender Blues Jr / Pro Jr Retube KitBrand New JJ EL84 Matched Pair and JJ 12AX7/ECC83 Trio The JJ EL84 has nice mids, sparkling highs and solid bottom end characterize this tube.The JJ 12AX7/ECC83 is a well balanced, higher gain preamp tube, that is not as noisy even given the larger plate structure. Great value for the money.Our Matching Policy At Tonal Tubes we match tubes using a tester that enables us to match tubes at high plate voltages as well as various bias voltages. This means that when you install these tubes, they will be a tight match inside your amplifier.We have very strict standards when it comes to matching. We match power tubes within 5% for plate current and 10% for transconductance. Most other retailers will match to just one of these values, however it is important to have both of these values matched. This is not a simple process and does take lots of time and dedication since tubes can vary so much from the factory.Having matched power tubes is important because it reduces hum from your amplifier. It also allows you to get more life out of your tubes, since each tube will be working approximately the same amount.
