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. \u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eOUTPUT TUBE SWITCHING KEYS\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eOutput 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.\u003c\/p\u003e\n\u003cp\u003e\u003cimg alt=\"woo-audio-wa234mono-headphone-amplifier-tube-keys-set\" data-image=\"https:\/\/images.squarespace-cdn.com\/content\/v1\/56a27b6e2399a3d8d9bfa52a\/1471910477151-K5VY441V4B488LCYYBQ1\/ke17ZwdGBToddI8pDm48kMKkcW2Wt7zF2_4JhdCZauNZw-zPPgdn4jUwVcJE1ZvWQUxwkmyExglNqGp0IvTJZamWLI2zvYWH8K3-s_4yszcp2ryTI0HqTOaaUohrI8PII8cSi_iTg8IZChtln4ybMNdrl7hkvM7FRXffaHblFRkKMshLAGzx4R3EDFOm1kBS\/woo-audio-wa234mono-headphone-amplifier-tube-keys-set\" data-image-dimensions=\"769x513\" data-image-focal-point=\"0.5,0.5\" data-image-id=\"57bb924bf5e23115c18d341d\" data-image-resolution=\"1000w\" data-load=\"false\" data-src=\"https:\/\/images.squarespace-cdn.com\/content\/v1\/56a27b6e2399a3d8d9bfa52a\/1471910477151-K5VY441V4B488LCYYBQ1\/ke17ZwdGBToddI8pDm48kMKkcW2Wt7zF2_4JhdCZauNZw-zPPgdn4jUwVcJE1ZvWQUxwkmyExglNqGp0IvTJZamWLI2zvYWH8K3-s_4yszcp2ryTI0HqTOaaUohrI8PII8cSi_iTg8IZChtln4ybMNdrl7hkvM7FRXffaHblFRkKMshLAGzx4R3EDFOm1kBS\/woo-audio-wa234mono-headphone-amplifier-tube-keys-set\" data-type=\"image\" src=\"https:\/\/images.squarespace-cdn.com\/content\/v1\/56a27b6e2399a3d8d9bfa52a\/1471910477151-K5VY441V4B488LCYYBQ1\/ke17ZwdGBToddI8pDm48kMKkcW2Wt7zF2_4JhdCZauNZw-zPPgdn4jUwVcJE1ZvWQUxwkmyExglNqGp0IvTJZamWLI2zvYWH8K3-s_4yszcp2ryTI0HqTOaaUohrI8PII8cSi_iTg8IZChtln4ybMNdrl7hkvM7FRXffaHblFRkKMshLAGzx4R3EDFOm1kBS\/woo-audio-wa234mono-headphone-amplifier-tube-keys-set?format=1000w\"\u003e\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eHighlights\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cul data-rte-list=\"default\"\u003e\n\u003cli\u003e\n\u003cp\u003eMonoblock design\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eTubes: 13EM7 driver x 1, 300B power x 1, 5U4G rectifier x 1 each amplifier\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eCompatible with 2A3\/300B\/45 power tubes\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eSingle-ended Triode, Class-A\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eTransformer-coupled, Point-to-Point wiring\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eIndependent headphone and speaker circuity\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eSelectable Cathode or Plate output with KEYS\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eAnodized aluminum chassis, available in Diamond Black or Platinum Silver\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003ePolytetrafluoroethylene (PTFE) tube sockets\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eSelf-biasing with compatible tubes [\u003ca href=\"https:\/\/docs.google.com\/spreadsheets\/d\/1DdsZyTx3CJv9_cG9kVdCGZap-AldiTsvuY4Ms1K_p3k\/pubhtml\" tabindex=\"0\" target=\"_blank\"\u003echart\u003c\/a\u003e]\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eDimensions without tubes: 10\" (H) x 8.75\" (W) x 13.25\" (D), 60 lbs. \/ 254mm (H) x 222.25mm (W) x 336.55mm (D), 27.21 kg.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eVoltage (100v–240v) factory configurable\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eDesigned and assembled in New York, USA\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eThree-year limited warranty [\u003ca href=\"https:\/\/wooaudio.com\/faq\" tabindex=\"0\" target=\"_blank\"\u003elearn more\u003c\/a\u003e]\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\u003cstrong\u003eIn the box\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cul data-rte-list=\"default\"\u003e\n\u003cli\u003e\n\u003cp\u003eQuick start guide\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eWA234-MONO amplifier x 2 [left and right channel]\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eWA234-MONO KEYS system [full set] x 1\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e13EM7 vacuum tube x 2\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e300B vacuum tube x 2\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e5U4G vacuum tube x 2\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e*AC power cord and audio cables are not included\u003c\/p\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003ePower Output:\u003c\/strong\u003e 8W @300B, 4W @2A3, 2W @45\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFrequency Response:\u003c\/strong\u003e 5 Hz -
