Review: JJ, always excellent - ECC81/12AT7, perfect for my application.
Review: The Vacuum Tube is good but... - ... but if desertcart delivers it in a normal cardboard box without any protection, the transport can damage it. In fact I just received 2 of them, the first blew in 10 seconds (and it is installed in a studio microphone microphone, not in amplifier, so not stressed at all). The second seems working fine as expected.

## Questions & Answers

**Q: Will these make my 15 watt Vox Night Train sound much better?**
A: Depends upon the condition of the existing valves in your amplifier. If the valves are well used and near the end of their life there ought to be a significant improvement. If they are new and the original valves supplied as stock you might perceive there to be some improvement but I would doubt that it would transform the amp in such a way 
it could be described as being "much better".

## Customer Reviews

### ⭐⭐⭐⭐⭐ JJ, always excellent
*by G***H on 8 September 2024*

ECC81/12AT7, perfect for my application.

### ⭐⭐ The Vacuum Tube is good but...
*by R***B on 25 January 2021*

... but if Amazon delivers it in a normal cardboard box without any protection, the transport can damage it. In fact I just received 2 of them, the first blew in 10 seconds (and it is installed in a studio microphone microphone, not in amplifier, so not stressed at all). The second seems working fine as expected.

### ⭐ Noisy
*by M***E on 30 December 2023*

Bought to replace a tube that had started to fail in a guitar tube combo as it had become noisy and occasionally had volume drops. Swapped it with one of the other tubes in the amp which confirmed it was only this tube that had issues. Unfortunately this JJ tube was even noisier so had to return it for a refund. Not sure if it was damaged but will now try a different brand instead.
