HI-END TUBE AMPLIFIER

AUDIOPHILE 300B/2A3 TUBE AMPLIFIER

Project in progress – Building

These days, I have a Class A single-ended tube amplifier on my workbench. This Japanese design is based on the legendary 300B triode or the equally superb 2A3. I am using many upgraded components in this project – such as Audio Note tantalum resistors and excellent Lundahl output transformers found in amplifiers costing five figures. What will be the result? I invite you to watch a photo report on the construction of this magnificent amplifier.
