I built my first radio receivers and other electronics back in 1980s when attending the elementary school, then took a 20 year leave from electronics to complete my education and pursue a successful business career.
In 2009, I returned to DIY audio by building a tube power amp kit and shortly thereafter started a blog on diyAudio.com. Ten years later I am migrating the blog to Google's Blogger with a view to preserve the availability of the blog and previous posts, and to keep posting new material.
