Products M50 Stereo Power Amplifier

M50 KT88 Stereo Power Amplifier
Built Around KT88 Tubes:
We built the M50 power amplifier around four KT88 tubes under an ultra-linear circuit that could provide 50 watts of subtly textured music. On good recordings you will hear height and depth. Tones retain their color and body. To get the most out of the design, we used the best caps and resistors we could ever find. The custom wound output and power transformers were specially designed to extend the bass and highs. Just as important, the military grade epoxy circuit boards are designed to minimize component interaction. You will also see the care we took by looking inside. No rat's nest here, neatly laid out Teflon wires, carefully thought through grounding paths, all done in the best traditions of American craftsmanship.

Special Features:

  • Pure Class A Ultra-Linear design.

  • Oversized hand wound power and output transformers (custom made in USA).

  • Custom gold plated brass five-way binding posts.

  • 100% handcrafted in California, USA.
