The Collins PP-3990/KWM-2 PP-3990/FRC-93 military power supply for the KWM-2 transceiver, when purchased "as-is PM-2," carries both potential advantages and disadvantages. Here are some factors to consider:

1. Potential Cost Savings: Buying the power supply as-is may offer a significant discount compared to buying a new one. This could be an attractive option for hobbyists or collectors on a budget.

2. Availability: It might be challenging to find a new power supply for older models like the KWM-2. In such cases, an as-is option could be the only viable choice.

1. Unknown Condition: Since it's an as-is item, the power supply's condition is uncertain. It may require repair or replacement of parts, which could negate the cost savings.

2. Lack of Warranty: Given that it's a used item, it likely won't come with a warranty. This means any repairs or replacement costs would come out of your pocket.

3. Compatibility Issues: There's a risk that the power supply may not work perfectly with the KWM-2 transceiver, especially if it's been modified or improperly maintained.

While purchasing an as-is Collins PP-3990/KWM-2 PP-3990/FRC-93 military power supply for your KWM-2 transceiver might seem appealing due to potential cost savings, it's crucial to weigh the pros and cons carefully. If you're comfortable with the risks and are prepared for potential repair costs, it could be a viable option. However, if you're not comfortable with the uncertainties and want peace of mind, it might be better to invest in a new power supply.

If you're a beginner or don't have much experience with electronics repair, it might be advisable to opt for a new power supply to ensure compatibility and reliability. For more experienced users, an as-is power supply could be a cost-effective choice, but be sure to thoroughly research the seller and inspect the item before purchasing.

Details:

Manufacturing technology was not the same as it is today so imperfections should be expected. The previous owner kept notes on nearly everything as it seemed to be his life-long hobby collect, test, and document he owned. Power cord was deteriorated and crumbly, so we cut it off. The previous owner was a Ham Radio operator who collected all of these interesting items over the years.
