Warm Audio WA-2A Opto Compressor

The WA-2A is a high-voltage, Class-A opto-compressor, utilizing large-core CineMag USA Transformers, four premium vacuum tubes, and the legendary Kenetek opto-cell - considered by many to be the world’s finest.

The WA-2A operates on four tubes: two 12AX7’s, one 12BH7, and one 6aq5 (or 6P1J). We proudly use Tung-Sol and Electro-Harmonix brand tubes in the signal path, which sound very 'open' and LARGE. All 4 tubes are socketed for easy swapping and replacement.
