61 AC&W T-80 Turntable Change
In late Nov 57, a marked increase was noticed in the vibration of the antenna assembly of the Type 80 radar equipment. A representative of Currans, Ltd., manufacturers of the turntable, inspected the turntable and found the bearings chipped and scarred. From this it was deduced that the track was similarly damaged. As a precautionary measure, the Type 80 was placed on standby status, for use only during emergencies. Decca was approached and set up the mechanics for removal of the antenna assembly and replacement of the turntable. Arrangements were made for immediate release of a MK III turntable from Air Ministry. Estimated cost of repairs was to be $75,000 and AFHQ was requested to increase CD 575761 by that amount. A contract was let by DDP to the Ministry of Supply to cover actual work performed and charges for preliminary work carried out by Decca. The replacement of the turntable was completed by 3 Apr 58 without incident. Total cost of the change was estimated to be $121,520.69.
