Our Best Choice: NE5532 Stereo Preamplifier Volume Control Board with Treble Midrange and Bass Tone Controls DIY Kit Preamp Module
High quality filter power supply. The four pins of rectifier respectively in parallel connect with decoupling capacitor, which can effectively eliminate the high frequency interference of AC power grid. Two 2200UF25V electrolytic capacitor filter the negative power supply, then stabilize voltage with 7815 and 7915 double DC power supply. Now the clutter interference of power grid is very small and the voltage is quite stable. So the item has better performance.The chip has high conversion rate and strong drive ability. The frequency band is wide and noise is very small.
1, The amplifier board can not use 12 V battery or DC directly as power supply. Power supply should be positive and negative double DC power sources, or special AC 12 V transformer power supply.

I built this as part of my home-build 200 watt amp system. I haven’t installed it yet, as the build is on hold for additional parts. Once I do installed it I will write another review as to its performance.
The way I use these types of products is that I start with a 19 inch rack mount 2U or 3U chassis and I’ll stuff a toroidal transformer, a full wave bridge rectifier and filter cap board, an input selector board (+15vdc), a speaker protection circuit board (+12vdc), a blue tooth receiver board (+5vdc), this preamp/tone board (+/-12vac**), a low pass filter/subwoofer summing preamp (+/-18vac), a dual channel VU meter driver board (+12vdc), a dual channel fixed gain current amplifier that drives the L/R speakers w/200w @8ohms (+56vdc) and finally a single channel/mono current amplifier the drives a passive subwoofer w/500w @4ohms (+48vdc). And sometimes the person who commissions the custom built amp wants to play some vinyl, I will add a RIAA phono preamp (+15vdc)
I build professional quality products using a modular approach. I chose this preamplifier because it was a do it yourself kit, and uses a very popular and very stable operational amplifier (op-amp) that provides good gain, A very good signal to noise ratio, acceptable harmonic distortion, good input impedance and with a 400-600mV input signal this will easily drive ‘any’ amp board you choose.
