Equipment Articles

These articles discuss specific pieces of equipment, including gear from the Crasno collection, my own designs, and interesting repairs for customers. The focus is vintage audio / musical devices such as keyboards and tape recorders, but also classic test equipment. Some items have especially thorough articles where information from other sources is scarce, yet the item is interesting enough to justify it. My hope is to aid in preservation and appreciation of old electronics, and to encourage new equipment to be designed and built to the same high standards.

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 metals, corrosive liquids, and so on.
