Fender Bassman 100T Retube Kits

Fender Bassman 100T Full Retube Kits. Regardless of your style and application we have you covered!

All of our Bassman 100T full Retube Kits are designed specifically for these amps. Every kit is configured to provide a specific sound/experience. The default power tubes are the JJ 6L6GC’s but you can use the drop down to select the JJ 5881’s. The JJ 6L6GC’s will maintain the OEM headroom/breakpoint for the output stage. 6L6’s are known for their bold cleans, deep bass, crystalline highs, and naturally scooped mids. The JJ 5881’s will drop the amps output power by about 20%. 5881’s have less bass extension, a crunchier mid-range, and bright jangly highs that compress when pushed.

These amps have the new auto bias feature.

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 quad of JJ 6L6GC’s by default, two Standard ECC83S’s for V1, V2, and one current Balanced JJ ECC81 for the phase inverter in V3, closest to the power tubes.

The High Gain Retube Kit uses the Handpicked High Gain JJ ECC83S’s for more punch and more growl! The Kit includes one matched quad of the 6L6GC’s by default, two Standard handpicked High Gain ECC83S’s for V1, V2, and one current Balanced JJ ECC81 for the phase inverter in V3, closest to the power tubes.

The ECC803S Option Retube Kit The JJ ECC803S is a long plate 12AX7 variant. These are a little lower in gain than the go-to JJ ECC83S. They have a very fat mid with more top-end which gives them a very vintage tone with lots of chime. This kit contains a matched quad of the 6L6GC’s by default, two Long Plate Standard JJ ECC803S’s to replace the 12AX7’s and one current Balanced JJ ECC81 for V3 closest to the power tubes.
