Marshall 2555X Tube Set

The Marshall 2555X Tube Set consists of 3 x 12AX7 preamp tubes, and 4 x EL34 power tubes.

The Silver Jubilee Series was created in 1987 to celebrate the 25^th anniversary of the founding of Marshall Amplification and the 50^th year of Jim Marshall being in the music business, hence the Silver Jubilee’s original ’25/50’ designation. The limited edition, all-valve Silver Jubilee amplifiers looked stunning in silver vinyl covering with chrome-plated control panel.

Based on the JCM800 2203 and 2204 Master Volume models, the Jubilee amplifiers were the first Marshall products with Pentode/Triode switching, which halves power output.

The Jubilee Series featured an innovative, if somewhat unusual, preamp circuit which had three gain modes: Clean, Rhythm Clip, and footswitchable Lead Channel.
