hi there Serge.. we are still waiting to hear from the techs concerning the 6500 technics. i think they were going to look at much the same as you suggested here... that was supposed to be today. its now evening and i havent heard back from them. i doubt whether they were successful, but we live in hope. will let you know either way.
In the meantime we are in the process of buying a Tyros4.. i need to ask... does anyone know where the serial number is on these keyboards please?? i want to know the serial number before i buy anything online. thanks so much...all input is greatly appreciated .
