Title: [X120CAH] Letter, 1883-1884
Editor's Notes: [TAE autograph; SELECTABLE IF WE CAN PINT DATE AROUND MAY 1884--SEE NS84ACK1] "the Gold & Stock want a dynamo to run their stock ckts, each circuit is 150 ohms & there must be 1.25 amperage on it. Want 10 or 15 pct extra volt margin. There are 50 circuits but at times another 50 circuits are put on ie the printing lever circuit but as this is only 1/5 the time and the current on the other magnet are closed it won't heat the machin very much so I think you could figure on 50 ckts. What machine & winding whall be used. Answer quick.
