It took less than an hour to build, more time to figure out the location in the Sony base etc!</p> <p>With the 9300 I used it externaly with a separate power feed.</p> <p>I cannot justify aquisition of a B&amp;O unit as my meagre collection of vinyl is old / scratched etc and this unit of course was free!</p> <p>I have a simple circuit for cleaning and stabilising the power supply - if anyone wants a copy pm me!</p> <p>salut</p> <p>Tony</p><div style="clear:both;"></div>
