Delay lines can come in various forms. I had abig 2200 (Marconi, gertting forgetful) and that had two big panels at the rear populated by Cs and Ls. There were others similar. Reference was made to 70' of twin coax. I would guess that two 35' lengths of single would also do, with the two "balancing out".
Telequipment used a block (say 4" x 2" x 1/2" with finely coiled up two contra wound coils. If you fail in successfully repairing your D/L, I think I have a spare block somewhere, though it is untested. Probably just needs continuity and insulation checking).
