zal Posted May 13, 2007 Share Posted May 13, 2007 Prea complicata ptr. puterea scoasa. Iese la fel de bine si cu piese mai putine.Parerea mea. :smt003 Link to comment Share on other sites More sharing options...

zal Posted May 17, 2007 Share Posted May 17, 2007 La tensiunea aia de alimentare scoate 50W/8ohmi. Poate a vrut sa zica 85W/4ohmi. :smt003 Link to comment Share on other sites More sharing options...
