Our favorite quote from Herb Reichert's review: "...you can build a world-class, four-star 300B tube amp that should cost $20,000 but will cost you only about $2000—because you've assembled it yourself."

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-8600S is included, except the tubes. Tubes are sold separately.
In the TU-8600S, 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-8600S will bring to light the outstanding characteristics of the famed 300B tubes.
The TU-8600 went together beautifully(like the other Elekit products I've assembled) and has been operating(thundering) flawlessly from the start.

The detail in the building manual is awesome with exellent drawings. The sound, one day after finishing the build is astonishing and as tubes and other parts 'burn in' will improve even further.

This was money well spent, and I had a lot of fun building this! Instructions were easy to follow and you really can't go wrong if you have just a bit of electronics knowledge. The resulting product sounds and looks fantastic, I tell you! As a bonus I love the fact that the output transformers are made in the little town of Norrtalje Sweden really near to where I was born.

Fantastic kit, fantastic amp. 2nd Elekit build and they both were super smooth. The 8200 is great but highly colored sound that works better w/ some music, while the 8600 is the sound that I have been searching for my whole life. I haven't even thought about putting my Yamaha A-S2100 back into the system and my digital only front end sounds deceptively analog.

Had a great time over the weekend building this kit. While not a stranger to rehabbing tube gear, I still found the quality of the instructions and packaging to be over the top fantastic. Fit and finish of the assembled parts are really a joy to behold. Best of all, the amp sounds fantastic! It's only been up and running a few hours, but I am very impressed with the detail and soundstage. Many thanks to TubeDepot for making this kit available!
