Dear Alan,
Thanks for this info.
I arrived less than one year ago to Washington DC, USA; before I was living in Stafford, Midlands, UK (near Birmingham).
I really miss the friendly, gentil and gentlemanly way to drive, but I prefer cars with right steering wheel

Probably in the near or middle future I'll move to Europe (may be France).
I decided to leave the jukebox in it's original 45 rpm and add a MP3 player, rather to add the 33.3/45 kit.
I started this projet today, so I'll post pics when it will be done.
I'll take off the bill acceptor front (only the plastic) an install there a 4.3" 9:16 touchscreen MP3 + FM radio player.
I Had evaluated to use a Android MP3, wifi 4.3" MP3/tablet, but today it only exist in android 2.xx, they have 4 control buttons in the side (difficult to access).
I'll connect the MP3 audio output to an small car amplifier (the mp3 output is not enough to feed the juke amplifier).
The car amplifier output will be connected to the stereo BGM (background music) input in my Amplifier Accessory Board (26694703).
I have a small problem, the juke do not cut the BGM music when a record is played.
When a touch the stylus (when there is no record playing) I can hear it, so the mute is not working, any advice how to fix it?
Thanks again
Claudio
