I have always been interested in OTL amplifiers. Vacuum tubes have excellent bandwidth and low distorsion without global feedback and resistance coupled tube amplifiers as used in pre-amps often don't use any feedback at all, as an example the distorsion of a resistance coupled 12AX7 with kohm anode resistance and V plate voltage is only 0. For power amplifiers a normal speaker is usually not directly connected to the output tubes, normal output tubes are high impedance devices that need to be connected to a load impedance in the kohm range to give high power. Normally an output transformer is used to transform the low impedance of the speaker to a more suitable load-impedance for the output tubes.

Now here is something completely different and new. Acuhorn OTL amplifiers with an intriguing approach A new solution for tube amplifiers output transformerless. It is a very interesting idea to apply 6C33C tubes operating at the utmost level of Amperes in the world.

The high level setup class A per tube is up 8 times greater. For example, in the S1 amplifier one tube per chanel works like traditional 8 tubes. Monoblock M4 is the equivalent of incredible 32 tubes. Acuhorn in its new amplifier series fused the newest technology with vintage audiophile tubes' qualities. The latest power supply technology breakthroughs.

The Vicor power modules as 10 times more excellently supporting splendid performance in audio. We have a powerful amplifier in pure class A, the beauty of the single ended triode in the audiophile way. Each tube operates independently with self-regulation. Input voltage mains autoranging Vac H ready for worldwide work.

The amplifiers include 21 Stepped Attenuator volume control - it is possible to connect without preamplifier. Easy to use - just insert the big tubes in their socket and start the music.


NEW Acuhorn amplifiers 6C33C tube output transformerless

SE 6C33C build. This topic probably been beat around alot, SE 6C33C build. So My start is a cache of 6C33C tubes, 2 Lundahl xfrmrs and 2 ripped apart tektronix type A power supplies. I am a tech and tube amp hobbyist I have built 4 or more guitar amplifiers from scratch And have rebuilt 2 Heathkit W5ms..

I don't know what kind of metal they use, but I had hard time to desolder (after the amps has been sent back for replacing the tube sockets with.

The output transformer has low insertion loss is very important , the best of the best is 0 dB Insertion Loss , The output transformers for High End tube amplifier need under 1dB Insertion Loss.

This article from respected author Ari Polisois deals with a single-ended amplifier with enough power to drive even the most difficult speaker systems - delivering 50W per channel. This is a project that quickly became the focus in lots of tube-oriented forums and has inspired long threads and many iterations, including further articles published in audioXpress from the author himself.

Review: Fluxion AV-7 Single-Ended 6C33C Amplifier

Young Ahn, a Korean-born electrical engineer, who lives and works nearby me, in the rural farmlands outside Brantford, Ontario Canada. Out here, ginseng has gradually replaced tobacco as the main crop, but it seems transistors have yet to replace vacuum tubes. A more interesting gentleman you will rarely meet in this hobby. And I should clarify: not only does Mr. Ahn hand-build each amplifier, he also designs all his circuits, and even winds all his own transformers. Yes, all the power and output transformers are all wound in house on a winding machine, and Mr.

You dont need to use step down transformer as using my amplifier. From now we can provide amplifier with wooden chassis based on order of customer.

The story about the reliable low distortion OTL amplifier

Sine I informed public about Melquiades amplifiers I receive many emails from people asking me about the operation points of 6C33C. For whatever reasons people mistakably took me for some kind of 6C33C guru, which is am not. Moreover I could be hardly be a consultant to any electronic engendering subjects, probably with an exception of the very narrow fields where I personally happened did something and was able mostly accidentally to reach some conclusive results. I do use 6C33C for years and I experienced it in many amplifiers, I like this tube.

I will be rebuilding this shortly using the same transformers and auto biasing as per the VMOS line driver, and will update this page accordingly. Vg bias of Output configuration to drive: ohm series, ohm parallel. Output impedance: 60 ohms series, 15 ohms parallel. Bandwidth: 25 Hz to 70 kHz. Noise floor: c.

Thank you very much for choosing Shuguang Audio Classic Series vacuum tube amplifier version. When opening the package, please carefully unpack all tubes and install each tube to its marked location.

When working on 8 ohm speakers, the power can reach to 40W 16 ohm speaker can reach to 50W , that means it can push most speakers very smoothly. Opened, detailed, pure sounds quality, it is very suitable to enjoy voice, orchestral music, light music, pop music, classical music etc. This model adopts precise potentiometers to accurately adjust the voltage through 6c33c grid. The circuit makes the mid-point voltage to 0 V, ensure the current via speaker equal to zero V. The secure design guarantee the safty of your high ended speaks.

Here I am going to describe something about how we designed our unique OTL amplifiers. OTL amplifiers have always had a reputation for excellent sound, the idea to be able to remove the output transformer with its inherent imperfections in a tube amplifier make it possible to design an amplifier with very high bandwidth and stability even with relatively high level of feedback. However, How do you really design an OTL amplifier with high reliability?

    You are not right. I'm sure. I can defend my position. Email me at PM, we will discuss.

  2. Athmore

    In this something is a good idea, it agrees with you.

  3. Jayson

    In it something is. Clearly, many thanks for the help in this matter.
