About the LM-129

The Line Magnetic AS-129 is a dedicated tube preamplifier, part of the brand's Analog Sound (AS) series and directly inspired by classic Western Electric 129 designs, using transformer-coupled input and output stages for a vintage yet high-performance presentation. It features a frequency response of 10Hz-20kHz (1W), input impedance of 100kΩ/600Ω, and gain of 9.6dB, and uses a tube complement of 4x 6J7 for amplification and 1x 5U4 as rectifier. The chassis is a substantial high-end build measuring 500x250x425mm and weighing 24kg, and the AS-129 has been offered in SG Series 2.0 / Limited Edition versions with remote control by SG Live Acoustics in some markets.
