First: diagnosis of the fault. With test tools such as an Oscilloscope, transistor tester, general AmpVoltOhm and logic analyser, most faults can be identified. Sometimes it can be hard to source replacement parts, particularly when they are mechanical or electronic components designed for a specific machine that ceased production perhaps 30 years ago!

Electronics designed in the 1970’s and 1980’s are typically repairable where components can be obtained, newer equipment, especially items with surface mount micro components sometimes can only be repaired if replacement circuit boards are available.

Power components and basic mechanical problems are more straight forward. Cheaper items such as effects sometimes are impossible to repair when build quality is poor or units are sealed.

 

An anti-static workshop area great care with beloved and sometimes very valuable items is essential. I’m happy to discuss or review any item and likelihood of success, free of charge, within reason!
