Overview

The WA234-Mono is the ultimate SET (single-ended triode) amplifier. The design is unlike any that the world has ever seen. The WA 234 unique design allows for us of legendary tubes like the 300B, 2A3 and 45 triodes. The choice of tubes offers the highest level of transparency and musicality. The WA234-Mono let you experience music like never before. You can now use any headphone and many high efficiency speakers. Whereas a typical tube amplifier allows you to use only one type of power tube (or a substitute with a similar rating), the 234-MONO increases your options in an elegant way. A tube-switching key (TSK) allows the amplifier to accept 2A3, 300B, or 45 power tubes, so you can instantly switch your tube to suit your music or your mood.

OUTPUT TUBE SWITCHING KEYS

Output switching key (OSK) allows the listener to switch between speaker and headphone output modes, making it possible to enjoy a piece of music through headphones, then immediately share it with friends through speakers. To make the 234-MONO even more versatile, Woo Audio created output-switching keys for cathode and plate outputs for high and low-impedance headphones.
