| X.2572. E C JUN 28 RECEIVED from BY.{R.W. Bailey - Chief Engineer} c. EFC. BY9-P28.6.20. X.2512 CHASSIS - CONDENSERS. ------------------- Referring to your memo EP{G. Eric Platford - Chief Quality Engineer}2/F22620 I consider that condensers as now being produced are more reliable than the early ones, in as much as the casings into which the condensers are fixed are now die castings with a smooth surface, whereas on the original type we used sand castings which were somewhat more rough. In addition to the improvement in the casing referred to above, I have instructed the Condenser Department to warm up the micanite insulating against which the Condenser is screwed up, so that the latter is not liable to get soft in service on the chassis and thereby reduce the end pressure on the screws fixing the Condenser and making the earth connection. I cannot believe that there is any need to get ourselves in a panic on this particular point, as the number of Condensers which have failed are very few and in any case I should certainly require some assurance that they were faulty in service, in the shape of failures occurring, before be begin to consider whether we shall send men all over the world to make modifications.
