- Editor's Notes
- [from London] "Each regulator of all the thirty treadle phonographs in your shipment to us of have proved DEFECTIVE & failed to GOVERN until REPAIRED. I found in every case the either the key on the shaft fitted too tightly through the slit of the regulator friction disc, or the [8?] holes for the screws which secrure the springs to the friction disc had burrs on the inside making the disk bind in the shaft." ## Also, battery cells get very hot. ## Suggests illegible improvement of fastening needles to the diaphragms.
