Used, in very good condition. Tested and works perfectly. This is one preamp that will help you reach for the stars without burning a hole in your wallet. The LS-7 is a straightforward, no-frills unit (its line stage only and no remote control circuitry) that packs four 6922/E88CC tubes. In fact, there are only two main controls on the unit input selection and gain control. When you peer though its top cover, the layout is simple but very effective. Specifications: Frequency response: 1Hz to 100kHz Total harmonic distortion: 0.01% Gain: 13dB (line) Signal to noise ratio: 102dB (line) Output: 2V (Pre out), 25V (Pre out Max) Valve complement: 4 x 6922/E88cc Dimensions: 480 x 134 x 260mm
