"F prranti Trickle Charger" MESSRS A. D. RILEY have sent to us for test one of their well-known trickle chargers. This is a, very neat arrangement, its dimensions being approximately 8 by.8 by 4, the terminals being arranged along the longer side. Tappings are being provided for 2, 4, and 6 volts. The measured output of this charger is .42 amps, and it will operate for approximately 100 hours on a unit of electricity, this latter. in most instances costing only 2d.
Used with an electrolytic condenser the, eharger could very successfully operate a moving coil loudspeaker, the consumption of which is approximately half amp. It will charge for very long periods without the slightest heating. Rectification is carried out by the Westinghouse metal rectifying unit.
