Audio Research - Model LS1 - High definition Stereo Line Amplifier in very good condition. Has not been used for about 8 years but working well the last time used. In technology, the LS1 draws heavily upon the proven hybrid circuitry used in Audio Research preamplifiers. A single 6DJ8 dual triode vacuum tube is used to provide most of the 20dB overall gain, while associated FET devices provide initial gain at input, and current gain following the vacuum tube. Power supply design is virtually identical to the SP9 pre-amplifier, giving the LS1 a lifelike sense of ease and dynamic expression. Looking to have buyer pick up. Ph
