About the 45
The Alan Eaton 45 Mono Blocks are a pair of custom-order, hand-wired, point-to-point single-ended Class A triode tube amplifiers. Each unit delivers about 1.5 watts into 8 ohms, designed with minimal components to preserve signal purity and reduce interference. Featuring vintage Orion power transformers, Tamura output transformers, silver Teflon-coated signal wiring, Electro Cube Mylar capacitors, Alpha gain controls, and military-grade Amphenol tube sockets. Built on custom 18-gauge steel chassis with powder-coated finish. Includes adjustable hum balance circuit, volume control, and power indicator. Compatible with standard line-level sources like CD players or DACs, no preamp required. Uses 45 output tubes, 6SN7 driver tubes, and rectifier tube (all tubes provided). Ideal for high-efficiency speakers (e.g., 97-98 dB). Some users report initial hum reducible via tube rolling or adjustments.
