The fair market price for a Nakamichi 630 FM Tuner Pre Amplifier in AUD is approximately $1,000–$1,500 for refurbished or very good used condition units, based on recent USD listings converted at current exchange rates (around 1 USD ≈ 1.50 AUD).

- Typical price range: $1,000–$1,200 AUD for standard used/very good condition; $1,300–$1,500 AUD for professionally refurbished units with servicing (e.g., recapping, cleaning, and full functional testing).
- Condition variations:
| Condition | Estimated AUD Range | Notes |
|--------------------|---------------------|-------|
| Used/Very Good | $1,000–$1,200 | Cosmetic wear but fully functional; e.g., Reverb listing at ~$1,080 AUD equivalent. |
| Refurbished | $1,300–$1,500 | Serviced to like-new performance; higher due to restoration costs. |
| New/Original Stock| Not available | Vintage 1970s item; no new stock exists. |

Key factors affecting value:
- Servicing history: Units with recent recap, cleaning, and certification command 20–30% premiums due to reliability in aging electronics.
- Cosmetics and originality: Inclusion of dust cover, cables, or original packaging adds 10–15%; scratches or missing parts reduce value.
- Market rarity: Low supply of working Nakamichi 600-series gear drives prices; demand from collectors boosts value.
- Regional/location effects: US-centric listings dominate; Australian prices may add 10–20% for shipping/import, though local HiFiShark equivalents align closely.
- Bundling: Often sold in systems (e.g., with 620 amp), inflating standalone value indirectly.
