These articles discuss specific pieces of equipment, including gear from the Crasno collection, as well as interesting repairs for customers. The focus is vintage electronics, including audio / musical devices such as keyboards and tape recorders, but also classic test and computing equipment. Repair tips and other unique bits of information are the usual features, and some items get especially thorough descriptions where information from other sources is scarce. My hope is to aid in preservation and appreciation of these old electronics. Note that I am still in the process of updating and transferring articles from my old website, JCS.
Warning: If you attempt any of the repairs or other procedures described, you are doing so at your own risk. I carry no responsibility for potential injury or damage, and give no guarantee that following my examples will result in success. Do not attempt anything without first understanding the dangers involved, which may include high voltage, high temperature, harmful radiation, toxic heavy metals, toxic and corrosive liquids, etc. Devices with a line cord or with vacuum tubes present especially high risk, especially old radios and televisions with "hot chassis" designs.
