    Previous earliest I've personally come across was a Yamaha RS7000
    sequencer, 2001 ,
    too early to mention the likes of RoHS or PbF etc anywhere on that.

    This time a Roland DB500 from 1999, the solder joints hazing over if you
    admix with leaded solder. Or is it some other solder formulation that
    can give a PbF+SnPb solder sudden-cooling + hazing appearance?

    I know it all started coming in , in Japan firstly.Japan passed the
    Electric Appliance Recycling Law, April 2001.
    And the soldering on every aspect of Sony's DCR-TRV 30 digital camcorder,
    released in March 2001, is "99.7% lead-free, including all supplied

    Anyone know what the Tick N225 compliance mark means, again on the back
    of an amp with dodgey solder.
    Latest component datecode 9940 and a pcb "7 segment" overlay date of 9945

    ** A mark like that is what many items I see have on them. The Tick ( for EM
    compliance) and a number starting with "N" refers to an importer in
    Australia, in NSW.

    So, in this case "Roland Australia" in Sydney.


    Looks like Roland print that number on everything.
