NXV200 R6 SE Amplifier Modules
We have brought back a very popular DIY audio amplifier module for a very limited production run.
Many hundreds of these module have been sold over the years all around the world and they use the Toshiba Power MOSFETs, 2SK1530 and 2SJ201, these devices are absolutely fantastic power transistors, with a single pair up to 200 watts into 4 ohms can be extracted, with very low THD+N and extraordinary bass control.
The net result is an amplifier that has wonderful 3D sound stage and sharp focal imaging, with smooth natural vocals and highs with rock solid bass response that rivals the very best amplifiers in the world. This amp module needs to be heard to be believed, it is that good!!!
A revamped PCB layout in the image of the NXL200 R5.3 has been produced as shown in the photos, The cost is shown below and it is for two amplifier modules, making them very cheap for such a hi-end power amplifier module.
The best of components have been used in its design, using Vishay MELF audio grade resistors and audio grade Wurth Electronics decoupling capacitors and Nichicon MUSE audio grade feedback capacitor.
The completed batch is expected to ship around Mid November 2023,
