[QUOTE="lemon, post: 1058135666, member: 16016"] Αν και δεν είμαι γνώστης των λυχνιών, νομίζω η απάντηση που αναζητάς περιέχεται σαφώς μέσα στο datasheet του μετασχηματιστή. Αντιγράφω : "[COLOR="#2F4F4F"]The LL1689PP is assembled with a small core air gap to allow for some DC current unbalance. For the S.E. versions of the LL1689, the core air gap is chosen such that the denoted DC current (18mA for a LL1689/18mA) generates a no signal core flux density of 0.9 Tesla when used with all primaries in series. This leaves a flux density swing of 0.7 T for the signal[/COLOR]." [/QUOTE]
