| CAR RADIO BULLETIN No. 1A. Published by the Philco Radio & Television Corporation of Great Britain Ltd; Perivale; Greenford; Middlesex. MODELS 806 & 806T. In a few of the above models it has been found that foreign matter may collect between the housing of the back plate and the main housing, which may cause a noisy background to reception. If this condition is encountered, it can easily be overcome by simply running solder into the two seams found at either end of the back plates, which are marked A and B on the diagram. [DIAGRAM] In some cases also the mounting bolt nearest the volume control may need two washers between the housing and the shoulder of the bolt, in order to prevent the bolt from shorting on the volume control. If you are not positive as to the identity of this bolt - use two washers on all three bolts to be safe. DIAGRAM TEXT: A, BACK PLATE, B, DOWN INTO SET WITH LID{A. J. Lidsey} REMOVED. INSTALLATIONS ON FORD V.8. The oil gauge on this model is electrically driven, and in some cases may require suppression, as may the roof light. This is easily done by connecting a condenser (Part No. 30/4007) from the live wire to earth. Replacement Parts on Models 11 & 11T. Should Part No. 30/2072B be found to have served its useful life, it will be necessary to replace with a Part No. 30/2072 and also part No. 7440. The Part No. 30/2072 is mounted in the usual position. The Part No. 7440 is mounted on the sub-chassis by removing the Kalon screw holding the Rectifier compartment screen, and mounting one lug underneath. The other lug is mounted by drilling a 1/8th hole (located by position of other lug hole) at right angles to screen and screwing in a self cutting Kalon screw. In some models two holes will be found in the chassis which exactly fit this condensers, and the method of fixing is then clearly shewn in the Service Bulletin covering the models 11 & 11T in the "Complete Technical Information Binder". The negative connecting lug on the 7440 should be earthed to the casing and the positive lug is connected to the cathode of the output valve. This condenser acts as a replacement of the blue lead (10 mfd) of the original condenser block. | ||
