Buna ziua ,am achizitionat, amplificatorul pma 730,si am observat ca unul din canale suna mai slab,bas , medii. Am curatat cu spray comutatorii din preamplificator-sunt tip claviatura-am observat ca de acolo vine problema,dar se pare ca schimbatul e solutia. As dori sa ma ajutati cu schema electrica , pe care nu o gasesc nicaieri ,poate decat cu plata.Intentionez sa-l restaurez pentru ca pe boxele Unitra de 75w suna excelent .Va multumesc!
