Silver Jubilee 2550 – 50W Head – 1987

Serial Number: S/A 03489
Inspection Sticker Date: 05/06/1987 – 5th June 1987

A superb example of a 1987 Marshall Silver Jubilee 2550 50-watt head, presented in very good vintage condition and freshly serviced by Dave Wittering of Prestige Amp Servicing.

Produced to celebrate Marshall's 25th anniversary and Jim Marshall's 50 years in the music business, the original Silver Jubilee series has become one of the most sought-after amplifier ranges in Marshall's history.

The 2550 combines the familiar punch and aggression of a classic Marshall with a distinctive, harmonically rich overdrive and the additional flexibility of the Jubilee's switchable rhythm and lead modes.

This example retains its original silver-grey covering, black grille cloth and distinctive Jubilee styling, with only minor cosmetic wear accumulated over nearly four decades.

• Dagnall mains transformer – replaced at some point with the correct specification Dagnall part

• Original factory inspection sticker dated 5th June 1987

Classic Silver Jubilee Tone

The 2550 Silver Jubilee offers a distinctive take on the classic Marshall Master Volume circuit, with a slightly smoother, more compressed response than a conventional JMP or JCM800.

The Rhythm Clip function provides additional gain and crunch, while the Lead mode delivers thick, saturated overdrive with excellent sustain and a particularly rich midrange character.

The amplifier features High/Low output switching, allowing operation at approximately 50 watts or 25 watts, making it a versatile alternative to the full-powered 100-watt 2555.

From classic British rock tones through to aggressive hard rock and singing lead sounds, the Silver Jubilee remains one of Marshall's most celebrated designs.

Cosmetic Condition

The amplifier is in very good cosmetic condition for its age, retaining its classic Silver Jubilee appearance.

There are a few minor marks, snags and small areas of wear to the silver-grey tolex, as shown in the photographs, but overall the amplifier presents very well.

The gold control panel shows some natural signs of age and use, entirely consistent with a vintage amplifier from 1987.
