naebv Posted January 22, 2012 Share Posted January 22, 2012 Montati de exemplu o dioda BY229 recuperata; de asemenea inlocuiti componentele din grupul paralel cu ea: C839, R837, D815. Link to comment
leoncris Posted January 22, 2012 Share Posted January 22, 2012 N'ar strica sa montezi o sarcina artificiala in locul finalului linii si sa'l iei (TV_ul) la puricat. Link to comment
