---

- NOS/NIB parts are typically more expensive than used or aftermarket replacements. The price may be significantly higher than equivalent modern or refurbished components, which could be a barrier for budget-conscious buyers.

- The IF transformer coil, being a specialized part, may cost more than a generic replacement, even if it is not used.

- Older components like these may lack modern documentation, schematics, or troubleshooting guides. This can make installation or repair more challenging, especially for those unfamiliar with vintage radio technology.

- Without clear instructions, there is a risk of improper installation, which could damage the radio or void warranties (if applicable).

- Even if the part is NOS/NIB, there is a chance it may not fit perfectly due to minor variations in design, connectors, or mounting. This could require additional modifications or adapters.

- The 262.5 kc IF transformer is tuned for a specific frequency range. If the radio you are working on requires a different intermediate frequency, the part may not be usable without modification.

- NOS/NIB parts are often handled more carefully than used parts, but there is still a risk of accidental damage during shipping, installation, or storage. For example, the IF transformer coil could be damaged if mishandled, especially if it is delicate or has fragile wiring.

- Some vintage components may contain materials that are brittle or prone to cracking over time, even if they appear intact.

- Unlike modern electronics, NOS/NIB vintage parts may not have access to customer support, warranties, or replacement parts if something goes wrong. This shifts the responsibility entirely to the buyer.

- If the radio or component fails shortly after purchase, you may need to rely on third-party sellers, forums, or experts for help, which can be time-consuming and costly.

- Purchasing NOS/NIB parts may contribute to the depletion of rare or irreplaceable components, reducing availability for future collectors or restorers. This could drive up prices further in the long term.

- If the part is stored for an extended period, there is a risk of degradation due to environmental factors (e.g., humidity, temperature fluctuations), even if it is unused.

- The NOS/NIB market can be prone to mislabeling or counterfeit items, especially for rare parts. There is a risk that the item you receive may not actually be NOS/NIB but rather a used or refurbished part that has been relabeled.

- The IF transformer coil could be a replica or a modern reproduction, which may not match the original specifications or performance.

- Working with vintage radio components often requires specialized knowledge, such as soldering, circuit analysis, and understanding of older tube or transistor technologies. Without this expertise, the project may become frustrating or unsuccessful.

- The 2090907-18 radio and its components may require additional testing or calibration after installation, which can be complex without the right tools or experience.
