    I don't know how they measure the delay between two cars in case of safety car .
    There is a sensor on the front wheel ( I don't remenber if left or right ) and the measurement has made
    between two dedicated rows along the circuit .Why not on the rear wheel ?
    Simple there is the traction control .
    Last year there was the Twing to "improve " the aerodynamics . It looked like a VHF dipole .
    I have no words . Too much SW .
    Fortunately there are " toys" just like PL 700B equipped with germanium transinstor !
    No SW , no uP but it sounds !

    The son in law of my hifi guru works in a company that works alu and so....
    After I will add dots ( decals ) on the knobs , because this type
    has no dots ( original ) . They look the same as PL 700 .

    Thank you !
    But many thanks to my hi fi guru for electrical repair and to
    his son in law for polishing handles and knobs .
    Curiosities found during the job :
    -Caps size looks different
    -Handles are made in zamak and not in alu
    -Knobs screws are used as a reference point for level pots ( from You Tube )
    So decals are useless .
    True ?

    It works and the sound is great by definition !
    Since my father doesn't want to sell PL 700 and he would give to my brother ,
    I need a suggestion for a good preamp for it .
    No PL4000 : I prefer Sing Sing instead restoring an other one .

    Nicely-done, Marco. I appreciate the extra work done to refinish the cosmetics to make it look as good as it sounds. And I like to hear of a vintage component with a story and some past history about it from the previous owner.
