I've been thinking about the best low power triode to build an audio pre-ampilfier with. After looking at the choices available on eBay I've become enamored with the WE 101D. I like the planar electrode configuration and it looks like an easy tube to build. The things that I'll redesign from the original will be the filament and the glass arbor mounting arrangement. The extra pins on the button pinch will make it much easier to mount and align the innards and make it more ridged and reliable.
I like directly heated cathodes so I'm going with thoriated tungsten as the emitter. The bulb will be of the straight wall variety instead of the tennis ball shape. From what I've read on the audio forums the WE 101D is still a highly regarded tube. We'll see how it all works out.
