These two have been called D & E and the letters put in the aluminium case. Their capacities are .218 & .234 m.fs.{F. Steele} Two condensers have been made up since, our having a capacity of about .4 m.f. this one is at present (Old Mica) being reduced in thickness to decrease the capacity. The other having a capacity of .19 m.f. the thickness of this condenser is only about .050 greater than the G.E.C. (New Mica) condenser. This one is being increased in capacity a little so as to be well within the limite as Mr. Coverley thinks they should try to get it a little higher. L.F. | ||
