How to choose a Chinese Tube Amplifier
Tube amplifiers, popular especially among musicians, have a lot to offer but picking one that’s ideal for you can be a challenge. Let’s take a look at some factors to consider:

- EL84 – Here’s a slightly smaller tube that offers less power and headroom when compared to the EL34 and it helps deliver less low end which is actually a good thing for smaller and more compact headphone tube amps.
- 6L6 – The 6L6 is a tube that’s synonymous with American amplifiers and they offer more headroom and sound clean. It provides a balanced sound across all frequencies and the end result is a lovely and warm lows with a bright top end.
- KT66 – KT66 is a tube you should definitely consider using if you’re looking for something that delivers a little more on the mids and still is able to maintain a balanced sound with clear and crisp sounding audio.
