20 WATT FLUORO INVERTER used tip3055
The transformer is wound on a ferrite rod 10mm dia and 8cm long.
Do not remove the tube when the circuit is operating as the spikes produced by the transformer will damage the transistor.
The circuit will take approx 1.5amp on 12v, making it more efficient than running the tubes from the mains. A normal fluoro takes 20 watts for the tube and about 15 watts for the ballast.

STK4038 bassed 60 watt audio amplifier circuit project and explanation
Using the STK4038X audio amplifier IC, can be designed a very simple high power and efficiency audio power amplifier . This circuit is manufactured by Sanyo Corporation and will provide a output power of 60 watts on a 8 ohms load or 4 ohms load with 0.008% distortion .
The output power that is provided by this audio IC , can be more higher , but with more distortion.
If you will use a 8 ohms load you must power this audio amplifier project from a dual +/- 40 volts DC power supply and if you’ll use a 4 ohms load you must power this audio project form a dual +/- 33.5 volts DC power source.
To prevent over heating the STK4038X audio power IC must be heatsinked on a good heatsink .
Also you must use a very well filtered power supply ( a 10000uF capacitor will be fine for this audio project) .
