Our Grading Guarantee
All equipment listed on this site undergoes a multi-point inspection by our staff. While we use a standardised 1–5 Grading Scale, please note that "pre-owned" implies some degree of previous life. We strive for transparency and use the following terms:
- Visual Inspection: Condition grades are subjective but applied conservatively. We provide high-resolution photography of the actual unit for sale (no stock photos). We encourage buyers to zoom in on all images as they constitute part of the formal product description.
- Functional Testing: Unless labelled Grade 1 , all units have been tested for power, input/output integrity, and basic mechanical operation. Vintage units (20+ years) are tested for "period-appropriate" functionality; unless specified, internal components like capacitors are original.
- "Fair" Exclusions: Items graded 1 (Fair) are sold strictly for parts or repair. These items are ineligible for returns, refunds, or "Item Not as Described" claims regarding their condition.
- Return Window: If a unit arrives in a condition significantly different than its assigned grade (e.g., a Grade 4 unit arrives with a shattered faceplate), you must notify us within 24 hours of delivery.
