THE FOUR-POINT FIELD CHECK

What to inspect before you buy

  1. Write down the exact model

    Manufacturer plates, revision numbers, wattage, voltage and included components matter for comparable research.

  2. Test safely

    Look for damaged power cords and obvious hazards; do not open mains-powered devices unless qualified. Power-on is not the same as fully tested.

  3. List the actual functions checked

    Describe channels, inputs, display, cassette movement, tuner behavior or missing knobs; disclose anything you could not test.

  4. Measure before you buy

    Heavy equipment needs protective packaging, adequate padding and sometimes special shipping arrangements. Estimate landed costs first.

Common deal-killers

These are not automatic reasons to walk away, but they should change your offer, cost allowance or confidence in the final sale.

  • Electrical hazards
  • Crackling or dead channels
  • Dried belts and capacitors
  • Heavy, damage-prone shipping

How to research a sale price

Write down exact identifying details and condition. Compare recent, closely matching completed transactions where accessible, noting whether accessories and shipping are included. Active listings show asking prices, not realized proceeds. Enter a conservative estimate in the calculator; don't treat a single exceptional sale as the normal outcome.

When to bring it home

Buy when the identification is strong, the condition has been checked, the price has room for repairs and selling costs, and comparable demand is credible. Pass or reduce your offer when multiple unknowns could erase the margin. A great object can still be a bad financial flip.
