The VELLEMAN K8060 200W Discrete Power Amplifier Kit is a high-performance DIY audio amplifier designed for demanding audio enthusiasts, musicians, installers, and electronics hobbyists seeking exceptional sound quality and powerful output. Built using a fully discrete amplifier design with premium Epitaxial Darlington output transistors, this amplifier delivers outstanding audio performance with excellent reliability and remarkably low distortion.
Capable of delivering up to 200W music power into a 4 load, the K8060 provides impressive output for a wide range of professional and home audio applications. Whether used as the main amplifier in a high-fidelity stereo system, the power stage of an active loudspeaker, a dedicated subwoofer amplifier, a guitar amplifier, or as part of a custom home theatre installation, the K8060 offers exceptional clarity, dynamic response, and power handling.
Unlike many integrated amplifier solutions, the fully discrete transistor design provides superior control over loudspeakers, improved thermal stability, and excellent long-term reliability. The amplifier achieves an outstanding damping factor greater than 800, giving precise bass control and accurate loudspeaker performance even during demanding musical passages.
The amplifier produces 100W RMS into a 4 speaker and 70W RMS into an 8 load, making it suitable for a wide variety of loudspeaker systems. A very low total harmonic distortion of only 0.02% at 10W (1kHz) ensures clean, detailed audio reproduction across the full frequency spectrum.
With an exceptionally wide frequency response of 3Hz to 200kHz (-3dB), the K8060 reproduces everything from deep bass frequencies to the highest audio harmonics with remarkable accuracy, making it suitable for both music playback and professional audio applications.
The onboard DC power supply monitoring circuit features an LED indicator for convenient operational status, while integrated overload and short-circuit protection help safeguard both the amplifier and connected loudspeakers from accidental faults.
The kit includes all necessary transistor insulating hardware, spacers, and mounting bolts, simplifying assembly and ensuring proper electrical isolation during installation onto a suitable heatsink.
For optimum thermal performance, Velleman recommends fitting the amplifier to either the HSVM100 pre-drilled heatsink or the S44/75 heatsink, depending on installation requirements. The amplifier is powered from a dual 25-30VAC transformer rated at approximately 120VA, providing ample power reserves for demanding audio reproduction.
Supplied as a self-assembly electronic kit, the K8060 offers an enjoyable construction project while resulting in a professional-quality power amplifier suitable for countless custom audio applications.
Whether you're building a high-power stereo amplifier, upgrading a subwoofer, designing an active speaker, constructing a guitar amplifier, or creating a custom home theatre system, the VELLEMAN K8060 delivers powerful, clean, and reliable audio performance.
