About the Transcendence 2A3

The ToolShed Amps Transcendence 2A3 is a single-ended, Class A stereo amplifier designed for audiophiles seeking exceptional sound quality with directly-heated triode (DHT) tubes. It uses a pair of 2A3 power tubes, driven by E180F input/driver tubes and rectified by a 5Y3g or 5R4 tube. The amplifier delivers approximately 2.7 watts per channel with a frequency response of 20Hz to 25kHz within +/-3dB and less than 1.0% total harmonic distortion (exclusively 2nd order) into 8 ohms. It features vintage Tamura OEM output transformers, a choke-regulated power supply, and dual-discrete tube filament supplies for excellent stereo separation. The construction is fully point-to-point hand-wired with premium metal-film and wirewound resistors matched to less than 0.5% tolerance. The chassis is made from 3mm etched and polished or brushed 6061 aluminum plates with a hand-polished, finger-joined figured hardwood base. Inputs include two switchable RCA inputs with 50k input impedance and a gain adjustment control on the faceplate that can serve as a volume control when no preamplifier is used. Output is via 8 ohm binding posts accepting spade, banana, or bare wire connections. The amplifier is designed and built in Greenfield, Wisconsin, USA, and comes with a limited lifetime warranty to the original purchaser (tubes covered for 30 days). Tubes are not included by default. The Transcendence 2A3 is noted for its vintage tube sound character and meticulous craftsmanship, appealing to enthusiasts of directly-heated triode amplification.
