About the A40
The Revox A40 integrated amplifier, produced around 1961 to 1965, is a compact stereo amplifier featuring 10 watts per channel output into 8 ohms. It uses four ECL86 tubes (premium Philips MiniWatt) and offers a frequency response from 30 Hz to 20 kHz with total harmonic distortion of approximately 0.5%. The design recalls the aesthetics of the Revox G36, with rotary knobs and a classic tube amplifier sound signature. It is a vintage tube amplifier known for its warm sound and modest power output, suitable for smaller listening environments or as a collector's piece.
