Horn loudspeakers

Tesla ARS456 horn loudspeaker is designed for outdoor wiring 100V (15W, 102dB, 350-3500Hz). It is widely used for street, railway station and other PA systems. I have replaced the paper capacitor with new foil capacitor.

Equipment for 100V

I have made a set of 5W amplifier and 100V transformer. This set is modular, so each unit can be used separately. Amplifier includes a module with MBA 810 chip. Power supply is 12V.
