Elekit TU-8600 300B SE Tube Amplifier Kit - Limited Run


(Tubes Sold Separately)

In eternal pursuit of amazing sound quality, Elekit has updated and improved its amplification power and feedback circuitry with the 300B SE Tube Amplifier Kit TU-8600.

What they developed is an amp with stunning sound quality and super low noise that can also be used with headphones.


Utilizing a high-efficiency, low magnetic flux leakage R-core, the rectifier consists of schottky barrier diodes that require shorter recovery time, resulting in a reduction in even negligible noise spikes. In addition, all power is stabilized to reduce residual noise as much as possible, resulting in a noise level as low as less than 1/10 of it’s predecessor, the TU-8300R.

This amp kit is perfect for all the DIY hi fi aficionados out there. Some of it’s additional features include:

• Power Circuit Enhancement
• Stable NFB Circuit
• New Active Automatic Bias Adjustment
• Driving 300B Tubes to Full Power
• Tube-friendly Design
• Ample Space for Larger Coupling Capacitors
• Output Level Selection For Headphones


Everything you will need to build the TU-8600 is included, except the tubes. Tubes are sold separately.

In TU-8600, the 300B tubes are heated after the indirectly-heated tubes have warmed up, resulting in a tube-friendly environment that will not overload tubes that haven’t been warmed up properly.


There are 4 selections of output levels to match your headphone choice


When completed your 300B SE TU-8600 will bring to light the outstanding characteristics of the famed 300B tubes.
