Heater Wiring

Plenty of 100W Marshalls out there with 20ga on the filaments.

That raises another topic.
The gauge on the transformer itself.
I was a bit surprised when I first got back into tube amps at the gauge of wire on the secondaries.
Of course those are very short runs so that may be why but they sure seem small.

I never measured the gauge on them but they can't be bigger than 20ga maybe 18.

The heater wires on my Pacific are pretty big...
