Loss of sensitivity on 5975 Bad Repeller?

Hmm We tend to favor position 2 because if we use 1 crap from the top falls on the bottom filament whereas if we use position 2 crap from it falls to the bottom of the source.

In any case the bottom filament looked a bit charred.

Filament 1 should be at the top of the source right? I'm a little confused.

Filament wires are labeled on the feed through board. Filament 1 wires (white?) are on top. They will reach to attach on the bottom if you want. On the 5975 you can watch it in action.

Yep Filament 1 has 2 white wires and is on top of the source Filament 2 has 2 black wires and attaches to the bottom. I suppose you could switch them but why?
