For Sale: Good quality TubeDepot kit built Model 16LS Stereo Integrated Tube amplifier with optional "Stereo Phono Preamp Tube Kit for L Series amplifiers".
Super clean, working perfectly. You can leave this as an open air amp or you can build a custom case for it. I did not build this but the person I got it from did a professional job. It's working 100% and has been fully tested with both line inputs and a turntable with a standard magnetic phono cartridge. It sounds excellent, no distortion, no static, no issues. The tubes appear to all be matched new/old stock GE made in the USA tubes originally provided with the kit. Previous owner says he used it for about 30 hours or so total so it's practically new. If requested will included free RCA cables and/or a 3.5mm to RCA stereo cable that you can use to plug in any MP3 player, CD player, or phone with a standard headphone jack. I tested this right after testing the turntable with a standard solid state amp and the same speakers - the sound from this tube amp was noticeably better to me, am usually skeptical but there was a definite difference in quality.
