Review on π΅ HIFI Preamp NE5532 Pre-amplifier Volume Tone Control Board Kits: Transform Your Audio Experience with this DIY AC 12V OP-AMP HIFI Amplifier by Jamie Sanchez
Terrible hum, fun soldering project.
Bought two of these. Both came with different capacitors, one with ceramic and electrolytic, the other with electrolytic only. Both produce an exceptional buzz. With the audio muted and just passing the audio through my amp it sounds fine, but none of the preamps I've bought can be used because they are so loud.
- OP AMP IC SOCKET: This preamp adopts op amp IC connector, flexible, easy to upgrade, suitable for various purposes.
- A small change
