At your risk.
Ears should be protected from high SPLs.
The 17KΩ collector to base biasing resistor has been changed to 10KΩ. A fresh 12V battery was used. Quiescent collector, speaker voice coil current increased to 280mA.
The Tesla drive unit quiescently defletcs more when battery is connected but it can operate as it is a high power handling speaker.
French wrench heat sink for 2N3055 transistor is getting warmed.
(Always use a fuse in series with battery for safety including fire hazard).
The sound is quite loud gombe heard satisfactorily in many rooms away from the listening room.
Saxophones on Jobim CD sound scaringlly real.
The transient of connecting power to 2N3055 transistor sounds amazing. This transient is so short it contains at huge frequency bandwidth.
