变压器作为电源，用线粗一些确实可以降低内阻。有人可能就要简单套用全电路欧姆定律，认为线粗可以大幅度提高输出电流的能力，带更多的负载。但变压器不同于电池，它要受到功率（容量）的制约，而这个功率的大小可通过铁芯尺寸来作一个基本评估，功率大铁芯一定会大。因为变压器二次绕组的能量是靠铁芯来传递的，由此可见对于铁芯尺寸已确定的变压器，只是一味的加粗线径并无多大意义。

所以提问中的灯丝绕组没有必要加粗，合适就好。因为胆机电子管的旁热式阴极对瞬间电压波动并不。具体线径可通过查表来获得，不低于下限就可以了。当然如果是自己绕制变压器，只要窗口允许，可以用粗一点的线，尽管好处有限但至少无害，不过成本也会高一些。
