RCA 6U8A/6KDB Tubes (NOS - New Old Stock) are vintage electron tubes that are still sought after for high-end audio applications. Here are some pros and cons to consider before making a purchase:

1. Authentic Sound Quality: NOS tubes are known for their warm, rich, and detailed sound, which many audio enthusiasts find more pleasing compared to modern solid-state components.

2. Durability: Since they are new but still vintage, these tubes have been tested and are in good working condition, ensuring a reliable performance.

3. Collectible Value: RCA 6U8A/6KDB tubes have a certain nostalgia appeal and can be considered a collectible item.

4. Improved Harmonic Distortion: Some audio enthusiasts claim that NOS tubes have lower harmonic distortion, resulting in a cleaner and more accurate sound.

1. Limited Availability: NOS tubes are not mass-produced, making them harder to find and more expensive compared to modern components.

2. Fragile: Electron tubes are more fragile and sensitive to handling compared to solid-state components, which can lead to shorter lifespans if not properly cared for.

3. Higher Power Consumption: Tubes consume more power compared to solid-state components, which can result in higher energy bills.

4. Warm-Up Time: Tubes require a warm-up time before reaching optimal performance, which can be inconvenient.

If you are an audio enthusiast looking for a unique and authentic sound quality, and you are willing to invest in a collector's item, then RCA 6U8A/6KDB tubes (NOS) could be a good choice for you. However, keep in mind that they are more expensive, fragile, and require more power compared to modern components. Additionally, consider the convenience factor, as tubes require a warm-up time and can be more sensitive to handling.

Before making a purchase, I recommend researching the specific model of the tube amplifier you plan to use these tubes with, to ensure compatibility. Also, consider purchasing tubes from a reputable seller who can provide a warranty or guarantee the tubes' quality. Lastly, be prepared for a higher upfront cost and the potential need for regular maintenance or replacement due to their fragility.

Details:

Everything you see in the pictures is what included this lot. Not saying it won't need adjustments but, looks like a nice clean unit. Please look at all pictures closely before purchasing. I did purchase from a local operator.

I am not an operator and don't have the knowledge to fully test myself. Items may need a more in depth cleaning. I do a lot of business with them and they always have well cared for gear. Photos are the best.
