Upon arrival we will be disassemble, diagnose and repair the unit, bead-blast and re-label the outer case to give close to an ‘as-new’ appearance as possible. Generally units are sent in because they have already failed, or are suspect but it is certainly not necessary to wait for a for issues to appear before sending the unit in. These units are ~40 years old and even when still functional, they often have degraded output power, behave intermittently, or die spontaneously.
