Can anyone comment on the sound ? I suppose it sounds pretty tube-like due to the feedback loop.

I'd be interested in a tube phase splitter for use in the BPA-300 amplifier. This could replace the expensive Jensen or Lundahl input transformer and or opamp input phase splitter that is necessary in this amplifier. I think a toobe would be a much better choice then either of the other routes. There are already kit amplifiers for sale from China via e-bay similar to what you guys are showing above.

Besides the possibility of counterfeit parts, any reason not to pick that up?
