I do amplifier servicing, design and modifications. This include amp repairs, retubing, power tube biasing, cleaning/replacement of scratchy pots/jacks, restoration/replacement of faulty, worn out and out-of-spec components, etc.
I studied Electronics Engineering at Curtin University of Technology from 1997 until 2000 as a mature student. I was already about 26 years old then and had already earned a Diploma in Electrical Engineering six years earlier. Electronics was easy because I had always been interested in it and had a keen sense of it. As far as I can remember I was always tearing up old radios and was pretty intrigued with them. I was always wondering what some of the components were and what they were for and how they worked. Of course, I messed around with the azimuth on the tape head to get the tape to play clearly. So going to school to learn electronics was a great fun because I found my questions answered.
We had a hifi boombox back when I was about 6 years of age. Back then was vinyl records and chrome/metal tapes. They were the hifi deal. My first record was the Beatles "Rubber Soul" and Christopher Cross. I remember the Beatles were originally recorded onto mono tracks at EMI, but the vinyl played stereo - so the right channel would have drums and vocals and the left channel would have guitars and piano or something.
My uncle was a hippie, and played simple guitar (Charley Pride, Bread, Johnny Cash, Neil Young, CSN, etc. comes to mind) and taught us some simple stuff to play. Music was also another great love. I did well in school and was given monetary awards and I bought my first electric - an 1989 Fender '57 reissue which I had to hide for fear of letting my father know what I had done with the money.
In my teens, I remember reading articles about how so-and-so artiste did their records in some famous studio with the pictures of them sitting on the consoles and I thought it was cool. And i wanted to have some part of it as my job or hobby. Later did I realise that part was called sound engineering.
In between my Diploma and Bachelors, I have worked as a Network Administrator at a Wireless Communication research centre for 2 years. After my degree stint in Curtin University I worked in the Defense sector as a Network & IT Security Project Engineer for 6 years and was given a high security clearance. After that, a half year stint as a Patent Engineer in a big South East Asian law firm; 2 years teaching Engineering Maths at a technical college as an Adjunct Lecturer and it was quite enough. I designed a home studio cum keyboard demo room for a Nord dealer and become a technical partner in the process, clinching distribution rights for the Muse Receptor and ICON studio products. I also built some heavy duty DAWs for well known producers and arrangers and designed a couple of guitar amplifiers.
I think I'm making one full circle going back to where I came from. I am still as curious and always trying to improve whatever electronics equipment I own.
