design was delivered to Radio Craft, Mathias suggested that a small Matamp logo be added. As a courtesy to Mathias, Cooper agreed to this request, making Matamp a model name. The first of the Orange Matamp amplifiers were 100 watt valve amps and were produced in very small numbers in the rear of a tobacconist shop owned by Mathias. Demand for Orange amplifiers grew quickly and Radio Craft was unable to keep up with orders. It became apparent that larger premises were required for business growth. Mathias was unable to finance the move at the time. In 1969, Cooper Mathias Ltd was formed to replace Radio Craft. Cooper's feeling was that a 50/50 partnership would be to the advantage of all parties, rather than to simply finance Radio Craft with the benefit of cheaper overheads in Huddersfield than in London. The central plan behind Cooper Mathias was to increase capacity and productivity to a level at which the service could be offered to other amplifier companies. 1970s The factory in Cowcliffe near Huddersfield was opened in early 1970. Mathias would drive from Huddersfield with a small number of completed amplifier chassis which would be fitted into sleeves, boxed, and despatched from the Orange Shop in London. At this time business in London was moving very rapidly; however, the situation in Huddersfield was much slower. Whilst visiting the factory for a production meeting, Cooper was struck by the slow pace of production. Large numbers of back orders meant that production at Cowcliffe was failing to keep up with demand and the low number of units being produced caused the operation to be non cost effective and not covering its overheads. The decision was taken to end Orange's relationship with Matamp. Cooper and Mathias remained on friendly terms despite the split, with Cooper describing Mathias as "a real gentleman for whom I have always had nothing but the greatest admiration." After the decision to cease production in Huddersfield, Cooper located premises in a derelict shop on the corner of Neil's Yard and Short's Gardens in the Covent Garden area of London. This move was to increase productivity and to provide more room for cabinet making, amp testing, and storage, with cabinets being produced on the ground floor and amplifiers in the basement. In 1971, whilst driving in London, Cooper noticed the new road signs being introduced into the UK used graphic symbols
