Review on Enhance Your Home Audio Experience with the FX AUDIO Tube Preamp: NE5532 Replaceable Tube and OP Amp Chip, Mini HiFi Stereo 6K4 Vacuum Tube Buffer Preamplifier with Bass and Treble Control, and RCA Cable Compatibility for Amp/Active Speaker by Lynn Cole

So my Seeburg Q100 rat was too far away to save, so now it's Bluetooth and a turntable. My ghetto blaster is on the porch lol. It sounded good, but lacked that old-school deep sound that you can only get with tubes. Given the price and good reviews, especially with the good old USA made bulbs, it really can come to life. The supplied tubes also give your system depth of sound. No question, it was fun. Just don't bother with the settings. You go well past half your bass and treble, it clips a little. So don't use it for basic controls. Set them close to the center by playing a little as you will see. You're playing an old-school non-remix and pre-recording the volume, you can get away with higher output settings.
