    In my oppinion if they’re is to be a next generation of wb2mp3, my sugestions would be to stop the back ground hum that can be heard when the volume is low & also between chosen tracks.
    Also that all of the units behave in the same way when the cancel/reject button is pressed
    Currently some wb2mp3 cancell all selections while others only cancel the track that is playing.

    hello and welcome to the forum

    concerning this hum, could you let me know if you use the remote pot ? could you also tell me if the wallbox2mp3 is inside the wallbox ?
    if so it could be intresting to try to wire the wallbox metal part directly to the GND terminal block of the wallbox2mp3.
    Indeed for some reasons it seems that a parasite signal is received by the amplifier.
    Doing such of thing would transform the wallbox into a metal shield for the wallbox2mp3 system

    Concerning the reject button, I’ve just not identified such a trouble but it should be easy to fix, I’m going to check that.

    Thank you so much for your feedback, now that our team has grown, we’ll have the necessary time to really improve the system

    Good evening Fabien

    It is good news that the forum is now working again, and also very good that you now have help in running things.

    I have now  fitted several  wb2mp3 units into the  inside of  Seeburg SC 1-4 consollete’s that use the original speakers,  also one inside a Rowe WRA 200 & another one inside a wooden box that contains all of the other necessary components, this has a pair of modern Sony speakers all of them have the same back ground hum.

    Perhaps a photo on the forum of your suggested ground wire from the metal body to the ground connection on the wb2mp3 may help others experiencing the same problem.

    Only one of them has had the external volume pot fitted as it was the first I had converted, I followed your idea from a YouTube video and fitted it to the coin entry plate at the top of the cover. Subsequently I figured out how to utilise the volume control switches that are part of the wallbox so did not require the external pot.

    Cheers Scudie

    Good evening Fabien

    Yes it would appear that the hum is from the left hand speaker.

    kind regards

    Bonjour Fabien

    Forgot to ask in the last post if you had identified anything with my question of the reject button cancelling all selections?  I tried yesterday disconnecting the remote cancell switch I had fitted, and with the cover off pressed the cancel button on the board /card, this made no difference it still cancelled all selections.

    Kind Regards Scudie
