Lundahl Small Size Tube amplifier output transformer, LL2766

LL2766 is a small size power output transformer for tube amplifiers. The transformer is available with different core air gap for PP or SE drives.
The transformer has a special high flux, low distortion audio C-core of our own production.
The LL2766PP is assembled with a small core air gap to allow for some DC current unbalance.
For the S.E. versions of the LL2766, the core air gap is chosen such that the denoted DC current (50mA for a LL2766/50mA) 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.
