Fender Excelsior Full Retube Kits. Regardless of your style and application we have you covered!
All of our Fender Excelsior full Retube Kits are designed specifically for these amps. Every kit is configured to provide a specific sound/experience.
The Default power tubes for these kits use the Special Double Mica version of JJ’s 6V6S-DM. The Double Mica modification has no effect on the sonics of the tube, it simply helps to reinforce the internal assembly to minimize the chance of tube rattle.
These amps are cathode biased and all of our Retube Kits are designed be totally plug-and-play.
The Standard Retube Kit is as close to OEM as possible. Maintaining the amps stock level of headroom and gain while providing a warm but even handed overall sound. The kit includes one matched pair of JJ 6V6S-DM’s, one Balanced JJ ECC83S for the phase inverter (V2, farthest from the input jack) and one Standard JJ ECC83S for V1.
The Gold Pin Retube Kit uses the JJ ECC83S Gold Pin variants to provide a smoother, creamier, and more singing overall sound. This option is less aggressive and has less “teeth” when driven hard. If you like a classic raunchy gritty overdriven tone, we recommend looking elsewhere… If sweet, open, and more refined is what you’re after this kit will do it. The kit includes one matched pair of JJ 6V6S-DM’s, one Balanced JJ ECC83S Gold Pin for the phase inverter (V2, farthest from the input jack) and one Standard JJ Gold Pin ECC83S for V1.
The High Gain Retube Kit uses our hand picked high gain selected JJ ECC83S’s. If you’re looking for maximum crunch and grind this is where you want to be. Sonically this setup is very similar to our Standard Retube Kit but with a little extra gain on tap. The kit includes one matched pair of JJ 6V6S-DM’s, one Balanced High Gain JJ ECC83S for the phase inverter (V2, farthest from the input jack) and one High Gain JJ ECC83S for V1.
The ECC803S V1 Option Retube Kit uses the Long Plate JJ ECC803S in the V1 position. The JJ Long Plate ECC803S has a little lower gain with big thick mids and a little more sparkle in the highs. The kit includes one matched pair of JJ 6V6S-DM’s, one Balanced JJ ECC83S for the phase inverter (V2, farthest from the input jack), and one Standard JJ ECC803S for V1 (closest to input jack).
The SRV Retube Kit uses the JJ 5751 in the V1 position. The JJ 5751 is a purpose built low gain 12AX7/ECC83 substitute. Stevie famously used these to eek out a little extra clean headroom, and you can too. Expect about a 25% reduction in gain, which is like having an extra click on the dial before breakup sets in. Great for clean players and pedal users. The kit includes one matched pair of JJ 6V6S-DM’s, one Balanced JJ ECC83S for the phase inverter (V2, closest to power tubes) and one Standard JJ 5751 for V1 (closest to input jack).
