Tube Filament Wiring, Completion

The filament wiring is now done.  Since the chassis is so narrow, it's hard to get good pictures of it, but this will give an idea.

The filament line just runs from the power transformer, to the pilot light bracket (left side in the photo), then across the chassis and to one of the output tube sockets. 

Then it goes to the other output tube and then the three preamp tubes.  Well, two preamp tubes and phase inverter, to be more accurate.

Another shot showing more of the whole run.  I tucked it against the chassis inside the little lip that is the bottom edge.

Thrilling, right?  Next time we'll have a lot more progress!
