Technolink TC-770LC High Gain Phono/Mic/Aux Preamp Cheap phono preamp I bought on eBay a few years ago. Besides being cheap, I got it mainly because it has the gain boost. It was over $100 when I bought it new but they're selling for $87 now- search "TEC TC-770LC" on that sight for more info. It is in good working order and cosmetic condition- see photos. I'm not using this in any of my systems and I'm trying to clear out stuff. $60 OBO includes shipping CONUS and PayPal fees.
