Beschreibung
Elekit TU-8400 is a DIY kit of a pentode single ended power amplifier.
Thanks to two operation modes and Active Automatic Bias circuit, you can use it with plenty of different power tubes like 6V6, 6F6, 6L6 series, KT88, KT90, EL34 (6CA7), 5881, 6550, as well as KT120, KT150 and even KT170.
This model is dedicated to be used with preamplifier, although front-panel located input is equipped with additional preamp module which allows to use it with your phone or portable music player.
The kit itself contains all elements including enclosure but except tubes.
