  1. You should add in that you need 3 new wires in the “parts needed’ section.

    1. Agreed. Added hook-up wire to parts.

  2. Is there a decent cartridge that wouldn’t require this amp? Like an ortofon perhaps?

    1. I don’t know of any ceramic carts that are pro quality. If you find one, then you may not need to do the preamp mod.

  3. I noticed you didn’t mention a couple of connectors that hold the body and back cover together after unscrewing. Should we assume you just disconnected them and reconnected them before putting the back cover back on? From the video, it almost looks like you didn’t reconnect them. Thanks.

    1. Yes. Anything not mentioned should remain the same.

  4. Thanks for the DIY! Is there a specific reason why you removed those particular capacitors? I tried the same mod with my handy trax and the only problem I’m dealing with is a bad reading when I’m calibrating on Serato. Vinyl sounds good but I have a little hiss and hum. All my grounds look pretty decent. I just have no clue which capacitors I need to remove off my circuit board.

    1. Those caps are removed to isolate the original preamp from the circuit. Removing them doesn’t add any ground benefit.

      Not sure on the the Handy.

  5. Thanks for the advice! I figured I had too by pass the original preamp. Would you be able to locate the right capacitors just by viewing a circuit board?

  6. Hey there, I did this Mod on the PT01 Scratch and I am not getting any sound now. Is this going to be the same as the PT01 since they are technically different?

    1. The are almost exactly the same. I made a new preamp for the PT01. I should have a few available by the end of the year. It’s a better preamp, and the mod is a lot cleaner.

  7. Awesome tutorials Flesh O.N.E. Thank you.

    After installing the Pyle preamp with M44-7, the signal fades in and out intermittently. I’m running it on the D.C. Power adapter too. The power lights fades when the sound does.

    Any suggestions?

    1. That isn’t normal. I would check all of your soldering connections. Hit them all again.

      Also, make sure you insulate the board and any exposed wire. Something could be shorting.

    2. Hey Jez, I’m having the exact same problem, did you find out what was wrong?

      Thanks, peace!

      1. Would it be possible to have Jez email, to find out if he was able to fix the problem? I have the exact same issue.
        Thank you.

  8. Thank you for your modification tutorials. A quick query, can I use a Pyle PP999 instead of the PP444? (I cannot locate PP444 in the UK but can get a PP999) Would the connections be the same in principle? I have an Ion Quick Play LP rather than the PT01 as they are difficult to come by. I can again imagine the principle of the mod is the same. I will be adding a battery mod at the same time. Any guidance is appreciated. Thank you.

    1. I don’t have a pp999 or an ion quick play.
      You’d have to figure out where those nodes are on your devices, and make sure the power supply requirements are the same.
