Elekit TU-8185 Stereo Tube Amplifier Kit
A compact vacuum tube amp with Triode-power pentode tube ECL85
The kit includes ECL805E x 2pcs, a highly reliable version of ECL85.
A compact body with a headphone jack on the front panel - you can enjoy its large scale sound not only from speakers but also from headphones / earphones.
- Two types of input terminals: The amp is equipped with a RCA pin jack for LINE IN and a stereo mini jack to which you can connect a mobile phone or a portable music player.
- Headphone feature: Enjoy music either from speakers or headphones. The amp corresponds to headphones with impedance between 8 to 600ohm. Adjust the output level by changing the positions of jumper caps.
- USB-DAC module PS-3249R (optional) can be mounted inside the amp, which enables connecting the amp to a digital sound source in your PC.
This is an excellent little amp for it's price. It uses 6GV8 tubes which are relatively cheap and sound great. The kit itself went together easily, it took me about 4 hours and worked on the first try. This amp is perfect for first time builders as it's not too complex and has very detailed instructions. I would recommend this kit anyone looking for something nice to stick on their bookshelf.
