Elekit TU-8900 Components Upgrade & The Reason I Sold it

Here we go for tube amplifier again!

I have this Elekit TU-8900 amplifier for a short time before I sold it. I was enjoying the music with this amplifier for quite a while, and I can say this amplifier is powerful enough to drive my 86 dB sensitivity speakers with lots of dynamic and bass slam.

This Elekit TU-8900 is popular because it is the cheapest 300B or 2A3 amplifier that still made in Japan. This amplifier was coming as a kit, meaning you should install it by your own with the included manual and all parts scattered. Since I bought it second hand, it is assembled from the previous owner already.

In this post, I don't think I would add the same review again because you can find many good reviews about this amplifier everywhere. What I will share to you is actually there are few components that can be easily upgrade for the better sound.

Let's check it out.
