I've got some plans in the works for a different incarnation building off this design, but it's pretty early on. I think that the Ear amps are very good sounding in any form, and represent a respectable value. An excellent balance of performance and reasonable affordability. You can do better, and you can spend more, but you had better be sure the rest of your rig is up to snuff, especially your source, or you may not realize any benefit.

Very nice, what does the extra tube do?

Thanks

It's a rectifier tube, forming the other half of the hybrid Graetz bridge.
