Wireless exciter – D471 demo

A demo of the 2SD471 audio frequency amplifier transistor. The circuit is a Slayer exciter, running to one of my ‘Walgreen’ pill bottle Tesla towers. Power is from a Nokia phone charger, rated at 3.7V 340mA. Various displays of the performance of this quite amazing transistor and showing the increase in field reception by the use of a dipole.
