Hifi OPA2134 General Purpose Preamp Stripboard Veroboard Layout


in my last post I made a RIAA preamp for my turntable and I decided I wanted to make a general purpose hifi preamp for iPods, PCs, and whatever else you need to plug into your HiFi

so here it is - based on the OPA2134 opamp (again)

although I haven't tried it for this, I'm sure it'll work well as a instrument preamp too

      yes you can use a 4558
      it's a line preamp so you shouldn't put a volume on it

    Hi Mr. Paul
    I've built an audio amp using LM3886 IC. I'm using an ipod with it but the output i'm getting is not loud enough. My questions are 1. can I use this preamp with my LM3886 based amp 2. can I use the same 24 volt power i'm using for the main amp for the preamp?
    Thanks in advance
