Marshall Silver Jubilee Half Stack 2555 and 2551
The Silver Jubilee Series was created in 1987 to celebrate the 25th anniversary of the founding of Marshall Amplification and the 50th year of Jim Marshall being in the music business, hence the Silver Jubilee ‚original designation. The limited edition all-valve Silver Jubilee amplifiers looked stunning in silver vinyl covering with chrome-plated control panel. Based on JCM800 2203 and 2204 Master Volume models, the Jubilee amplifiers were the first Marshall products with Pentode/Triode switching, which halves power output.
The limited edition all-valve Silver Jubilee amplifiers looked stunning in silver vinyl covering with chrome-plated control panel. The Jubilee Series featured an innovative, if somewhat unusual, preamp circuit which had three gain modes: Clean, Rhythm Clip, and footswitchable Lead Channel. The Bass, Middle, Treble and Presence controls, although shared between channels, were re-designed and offered more tonal variation than any other Marshall product had before. The 2555X circuitry is taken from original 2555 diagrams and has been checked against the 2555 head in the Marshall museum. With modern production techniques we were also able to make some improvements to the electronics. Switching circuitry has been improved to avoid a relay flickering problem found on some original 2555s. Improved (DC) heaters ensure no noise. The introduction of external bias points on the chassis for re-valving and servicing. Black fibreglass wires that are high temperature and high voltage resistant. And the multi-pin connectors have been improved with higher insertion force and current capabilities but remain PVC, just like the originals.There have been some feature improvements made to the 2555X. On the back panel the original 2555 had two speaker output jacks and a rather awkward Output Impedance Selector. For easier operation the 2555X has no selector and instead has five speaker output jacks ranging from 16 Ohm to 4 Ohm.
