Here is a chance to own and assemble one of these great little amplifiers for less.

The HPA-nxV200se module has been optimised to use the IRFP240 and IRFP9240 devices.

The Fairchild FQA19N20 and FQA12P20 can also be used with the same performance as the IRF devices. Also because the nxv200se uses these devices it has a small reduction in power output to better suit the SOAR ratings of these devices. The Toshiba 2SK1530 or 2SJ201 devices could be used if so desired, all that would need to be changed is a resistor value in the Vbe biasing network, to get the higher power output.

The HPA-.nxV200se kit comes now in one version only, the SMD devices are populated on the PCB and it is tested to ensure you do not have any problems getting the module working after you install the supplied IRFP MOSFET output devices, supply caps, and feedback cap and mount it onto your choice of heat sink and power supply to get it working.

Other than that the nxV200se is the same amplifier as the nxV200, only you get to do more of the assembly and you also get to save some money at the same time.

The nxV200se VFET-MOSFET Audio Amplifier Module is a very high performance, high end audio amplifier module which is biased into Class A/B.

Hundreds of man hours has gone into its research and development.

Don't be fooled by it's small size and use of SMD components, this is the best sounding and well engineered amplifier module on the planet in it's power rating.

Many of these modules have now been sold to very happy customers, not one of these clients that I am aware of has not loved the build and sound quality of this amplifier module.

Read the Testimonials and have a look at the Gallery and see for yourself what some of the those who have purchased the nxv200 amplifier module are saying.
