Description
LL1660 is an interstage / line output transformer for tube amplifiers. The transformer is available with different
core air gap for PP or SE drives.
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 LL1660PP is assembled with a small core air gap to allow for some DC current unbalance.
For the S.E. versions of the LL1660, the core air gap is chosen such that the denoted DC current (18mA for a
LL1660/18mA) 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.
