Technical Condition:
I'm an electrical engineer with 15 years of experience. This NAD 218 THX is not a "basement find"; it has been fully bench-tested, internally inspected, and physically serviced for long-term reliability.

Measurements:
​DC Offset: Measured at a near-perfect 0.001V (1mV). This indicates a perfectly balanced output stage and optimal component health.

​Input Stage Service:
The original plastic RCA input block (a known weak point on this model) was replaced with a brand-new one. Professionally soldered and mechanically secured to the chassis to eliminate future "wiggle" or signal dropouts.
Additionally, all switches and contacts have been treated with DeoxIt contact gel which restores and protects.

​Capacitor Health:
Internal inspection confirms the original Nichicon 85°C capacitor bank is in pristine condition. No bulging, no leakage, and zero evidence of thermal stress on the boards.

​Hardware:
Rear protective terminal cover is fully intact. All binding posts are clean and tighten securely.

Cosmetic Condition: The unit is in very good overall shape. There is minor scuffing on the front handles typical of a unit this weight; please see photos for detail

​Performance Characteristics:
​High-Current Power:
Driven by a massive Holmgren toroid transformer. Stable down to 1-ohm loads, making this the ideal choice for difficult speakers like Magnepans, Martin Logans, or vintage Infinity Kappas.
​THX Certified:
Delivering 200W+ per channel with the classic, muscular NAD sound signature and over 700W bridged.

​Shipping & Handling:
​The Double-Box Method:
This unit weighs nearly 50 lbs. It will be double-boxed with high-density foam corner protection to ensure the chassis and transformer are immobilized during transit.
​Insurance:
Full value insurance included.
​Local Pickup:
Available in the Wentzville / St. Louis area to save on shipping and ensure the safest hand-off.
