1973 Marshall Artiste 50W Amplifier

Marshall Artiste JMP 2040 Lead - Bass - Organ 2-Channel 50-Watt 2x12" Valve Amplifier Combo. I think the amp is handwired but can't swear to it. Cosmetically it is in a reasonable condition with a few scuffs and scrapes aquired over its 51 year lifetime The fromt grille cloth has a a couple of tears in it but there is no damage to the Celestion Greenback speakers. These are the quite scarce G12H model with 55Hz cones and four ridge spiders and typically found in Marshall ‘Artiste’combo amplifiers from the early 70’s, The amp has only had home use and none since it was serviced several years ago by Cyril Ryan the amp wizard at Audiotronix, Galway, as I switched to using a Boss Micro BR and headphones around that time. The price of these amps online range from Stg£1400 to Stg£1900
