Poate nu e nevoie de schema.Ati facut ceva masuratori?Care leduri palpaie, in ce combinatie?Verificati tranzistor final linii, cond de 1nF paralel cu C-E si lipiturile la traf linii.

Totusi, sursa scoate cei 150 V ? Ma refer la B+. Nu ati specificat asta.Desi sursa e stufoasa, verificarea ei pe sarcina artificiala se face usor.
