| X7700 RHC.{R. H. Coverley - Production Engineer} from EFC. c. Sft{Mr Swift}/Mr.Brock. EFC2/AD24.9.30. X.7700. EXPERIMENTAL CONDENSERS. Will you please put in hand a second set of three condensers of .21 .23 and .25 microfarads respectively, similar to those already instructed in our EFC3/ADL8.9.30. We are arriving at the conclusion that the condition of tungsten points after extended use is considerably better with rather lower value of the condenser capacity and also possibly that the ignition is freer from misfiring due to the higher H.T. potential available with the lower capacity condenser.
