Description
LL1660S is a version of LL1660 with internal Faraday shields to improve balance in phase splitting interstage applications.
The transformer is available with different core air gap for different driving tubes.
The transformer is wound with a special low capacitance winding technique to achieve best high frequency performance. The transformer has a special high flux, low distortion audio C-core of our own production.
The LL1660S is assembled with a small core air gap to allow for some DC current unbalance.
For the L1660S, the core air gap is chosen such that the denoted DC current (18mA for a LL1660S/18mA) generates a no signal core flux density of 0.9 Tesla when used with windings 2 through 10 in series. This leaves a flux density swing of 0.7 T for the signal
