Rockola Princess-WORKING PERFECTLY- thanks to Thierry

Hello! I would like to thank Klaus, Marc, Seeburg19, Nimko, Charly49 and above all Thierry !! After reading all your helpfull suggestions, I finally made contact with Thierry, in Luxembourg, who kindly took time from his busy schedule to visit my sick jukebox, and by careful analysis, established that the problem was as follows: when I adjusted the cam which plays on the three microswitches, I loosened the two screws holding the bank of three switches together...which allowed one of the OTHER switches to go out of adjustment and be permanently closed!! ARRRRRGH!

I learned a lot about how it works from Thierry- MANY THANKS!
