| X7700. RHC{R. H. Coverley - Production Engineer}, from EFC. c. Sft{Mr Swift}/Mr Brock. EFC3/ADL.8.9.30. X.7700. EXPERIMENTAL CONDENSERS. Will you please have made for experimental tests in connection with contact point life improvement, three condensers differing only from standard in their capacities which we want to be .21, .23 and .25 microfarads respectively. The best way we suggest to make these is to unwind three standard condensers until the capacity is reduced to the figures desired and then pack up the condensers with presspahn or similar material to fill up the space in the case.
