Pros of buying 4700umhos RCA tubes:

1. Improved picture quality: The higher microampere rating of these tubes can provide better detail, contrast, and color accuracy compared to lower-rated tubes.

2. Longer lifespan: The 4700umhos rating indicates that these tubes have a longer lifespan, which can save you money in the long run by reducing the need for frequent replacements.

3. Wide compatibility: These tubes are compatible with a wide range of television sets, including both old and new models.

Cons of buying 4700umhos RCA tubes:

1. Higher cost: These tubes are typically more expensive than lower-rated tubes, so the upfront cost may be higher.

2. Potential for burn-in: If you watch the same content for extended periods, there is a risk of burn-in, which can result in permanent damage to the tube.

3. Limited availability: Due to the niche market for high-end tubes, they may be harder to find in local electronics stores, and you may need to order them online.

Conclusion:

If you are looking for a tube that can provide improved picture quality and a longer lifespan, 4700umhos RCA tubes may be a good option. However, the higher cost and potential for burn-in are important considerations to keep in mind. Ultimately, the decision to buy these tubes depends on your budget, viewing habits, and the specific requirements of your television set.

Recommendation:

If you are willing to invest in high-end tubes for improved picture quality and a longer lifespan, 4700umhos RCA tubes can be a good choice. However, be sure to research the specific models available and compare prices to ensure you are getting the best value for your money. Additionally, consider using a tube protection screen to minimize the risk of burn-in.
