Bringing back DHT amplifiers.
We have been building tube amplifiers for 3 decades. Musica Bella is now bringing back custom built 45, 2A3 & 300B amplifiers based on the chassis/layout shown below.
We chose a larger chassis as many of the upgrades require quite a bit of real-estate such as polypropylene power supply and cathode bypass capacitors, even on the input tubes.
The Maple front piece is a completed amplifier. The Black unit is an AI rendering depicting what our amplifiers will look like.
A matching preamp will also be available.

Harmonia: Frequently Asked Questions

To assist our customers, we have compiled the following overview addressing the most common inquiries regarding the Harmonia output stage. We will continue to add content as it comes through.

Q: What is the Harmonia?
A: The Harmonia is engineered as a Directly Heated Triode (DHT) output stage designed specifically for source components.

Q: Which vacuum tubes are compatible with the Harmonia?
A: The Harmonia supports 45, 2A3, and 300B tubes. It features a user-adjustable direct current (DC) filament supply to seamlessly accommodate both 2.5V (45/1.5A and 2A3/2.5A) and 5V (300B/1.2A) filament voltages and currents.

A: The Harmonia is not a tube buffer stage. It utilizes a true Mu Follower circuit rather than a cathode follower, ensuring the complete, uncompromised sonic signature of the installed tube is fully realized.

Q: Is the Harmonia intended exclusively for solid-state systems?
