The 400v-100ma Supply Kit Dual Tube PS-4 4amp Vac Heath 6.3 Power Amplifier is a high-performance, vintage-style audio amplifier designed for audiophiles and music enthusiasts. This kit is an homage to the classic vacuum tube amplifiers that once dominated the audio landscape, offering a warm, rich sound that modern solid-state amplifiers simply cannot replicate.
The PS-4 power amplifier is a dual-mono design, meaning it has two completely independent channels to provide superior stereo separation and reduce crosstalk between the left and right channels. This design also allows for more precise tuning and adjustment of each channel, resulting in a more balanced and accurate sound.
The amplifier is rated for a power output of 4 amps, which is more than enough to drive even the most demanding speakers with ease. It uses six 6.3mm vacuum tubes, which are included in the kit, to generate the audio signal. The tubes are housed in a sturdy, heat-sinked metal chassis to keep them running cool and prevent thermal distortion.
The kit includes all the necessary components to build the amplifier, including a transformer, capacitors, resistors, and a high-quality, gold-plated output connector. The transformer is designed to provide a 400v AC supply to the tubes, ensuring that they receive the power they need to produce rich, full-bodied sound. The kit also includes detailed assembly instructions to help even the most novice DIY enthusiast build their own amplifier.
In terms of sound quality, the PS-4 amplifier delivers a warm, rich sound with a smooth, natural frequency response. It has a high power output, making it well-suited for driving high-sensitivity speakers, but it can also handle less sensitive speakers with ease. The amplifier is also capable of delivering a high level of dynamic range, allowing it to reproduce the subtlest nuances in music with clarity and precision.
Overall, the 400v-100ma Supply Kit Dual Tube PS-4 4amp Vac Heath 6.3 Power Amplifier is a high-quality, vintage-style audio amplifier that delivers a rich, full-bodied sound with a high level of dynamic range. It is a great choice for audiophiles and music enthusiasts who are looking for a unique and satisfying audio experience.

This is a wonderful testing and repair aid I used it to power the pp output in my mcintosh ma230 while I was improving the bias circuit for more headroom. Unit looks and performs like new. Minty as is often used on fluke meter not included for demo only.
