SUMMARY

The discussion centers on designing a low-noise 60W tube amplifier, specifically targeting resources for understanding tube circuits. Participants emphasize the need for in-depth literature on vacuum tubes, as traditional electrical engineering education often overlooks this area. A tutorial link is provided, but there is skepticism about the low-noise capabilities of vacuum tubes, with some suggesting that their inherent distortion may not align with the goal of achieving low noise levels.

PREREQUISITES
  • Understanding of tube amplifier circuits
  • Familiarity with vacuum tube technology
  • Basic knowledge of audio engineering principles
  • Experience with electronic design and schematics
NEXT STEPS
  • Research "The Art of Electronics" by Paul Horowitz for foundational knowledge on analog circuits
  • Explore "Designing High-Fidelity Tube Amplifiers" for specific design techniques
  • Investigate low-noise design strategies in tube amplifiers
  • Learn about the impact of second harmonic distortion in audio applications
USEFUL FOR

Audio engineers, hobbyists designing tube amplifiers, and anyone interested in high-fidelity sound reproduction will benefit from this discussion.

Hey everyone!

I have a project going on with a friend...a hifi tube amp! yeehaw!

Im going to start small the 60 watt range (30 per channel) and am wondering if anyone has any recommended reading for tube amp circuits, i need a book that gets right down into the dirt of tubes so that i can design it from the roots up with very low noise level and ideal configurations.

Any direction is greatly appreciated as I just got through my EE degree and we didnt even touch on vacuum tubes once...everything is solid state and digital it seems. grrrrrr not in the audiophile wolrd :D

Take good care all,
Dave

Here is a short tutorial on the internet:

Just a thought.. if you are going for low noise, vacuum tubes may not be the ticket. Most audiophiles I know like the sound from these units because they are not very clean. The second harmonic distortion does have a rather pleasant effect, especially with old Fender guitar amps.
