Rcd yr letters and telegram; have just wired you that trouble must be with a relay in that circuit somewhere, no condenser. But may be some bridge condensers has been broken or improperly connected. Gives instructions & diagram for diagnostic circuit. Can't believe that on such a short wire the signals of a fully condensed line would be as weak as you say. Re: the big magnets, you probably can't use them---they'd ruin the Morse. Do they have an armature adjustment for weakening strength of the iron? If needed, I'll come out for a few days.
