All credits to Mirko Ceronti (plcforum.it) the npn transistor can be a BC337 the pnp a BC327 the two left diodes 1N4148 the one that is in parallel with the 10ohm resistor a 1N4007 and the one in parallel with the load (8 ohm resistor) need to be a fast type and also high current. The mosfet for best results can be the irf3205. The mosfet is drove with a totem-pole driver and the inductance is placed to avoid noise at the ne555. 555. It is suitable for lights motors fans ecc. Enjoy.
