David Berning's "personal" amplifier revived nicely by Linear Tube Audio. It's a legit low-power amp, headphone amp, preamp rolled into one.

Critics (and most forums) love it. I like Dick Olsher's review (http://www.theabsolutesound.com/articles/david-berning-microzotl20-personal-amplifier/) because he also reviewed the original.
With original (unused) tubes, stock psu/cords. Purchased in September directly from Linear Tube.

Thanks (sorry for the one upside-down image) ....

Anand,
Those are the specs for the MZ2S model, which is a MicroZOTL2.0 modified to use the 12N7 tubes.
The MicroZOTL2.0 uses the 6SN7 tube for output.
It also comes with a switching power supply, not a manually switched LPS.
Cheers,
Steve

Got it. Specs are extraordinarily close though. Thanks for the correction.

Anand.

Yes, thanks for the cx. Anand, always feel free to ask the seller about specs...
