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

DIY-EK-TU-8600

(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.
