| Contd. -8- EFClo/T24.10.19. in spite of the fact that the gaps of the distributor were at least .020" and working on the leading corner. We have had to return from producting testing about 10% of all coils owing to these breaking down under conditions imposed by the tests, which fact would rather suggest that we must either improve the insulation or increase the amount of insulation at the ex-pense of secondary turns.
