| Contd. -2- EF R9/G13818. I will get Mr. Elliott to requisition some lengths of wire suitable for the drawing boards. I think they would do with about 6 to 8 c.p. lamps for 12 volts, highest efficiency that will burn regularly for, say, something over 200 hours life. Insulated wire for 5 amperes - 30 yards. Double Flexible for 1 ampere - 30 yards. Lamp Holders. - four Lamps. - six (until we see if the c.p. if right). Switches. - four - 1 ampere one - 5 ampere. Rough ammeter for reading up to 10 amperes so as to save the Weston, and enable it to use for volts. R.{Sir Henry Royce} | ||
