The three wires were fed from the three spools and wound as one wire; thus comprising the trifilar terminology.

三条线从三个线轴出来绕成一条线，从而符合三线并绕的要求。

Since the transformer is trifilar, the turns between the screen grids are fixed and correspond to the number of primary turns already calculated.

由于采用三线并绕，廉栅极绕组的圈数也是固定了，并且和上面所计算的初级圈数一致。

The three windings of this modified version of the McIntosh output transformer are wound trifilar, again with proper consideration given to polarities.

改良麦氏输出变压器的三个绕组采用三线并绕，当然，也需要考虑绕组的极性。
