I am an electronics hobbyst, a DIY guy taking care of all the techinical stuff at home (and friends' homes!). I love to use the hammer, drill machine, screw driver (to screw anything that I can lay my hands on) etc. Profesionally, I own a manufacturing/production unit for professional quality PA audio equipment like audio mixers, digital echo units, amplifiers etc. My experience in electronics spans about 30 years.
