Purchased two extra at CES - sold one, and will now selling the other.
Amp has not been used, it has its original tubes and matching 120 volt power supply, boxes and packing.
While listed as 10/10, this amp and power supply are NEW in their original factory boxes, and the warranty should be honored with a copy of my receipt.
Note, this is not an Earmax Pro. It is the Earmax which works WONDERFULLY with higher impedance headphones from Sennheiser, Beyerdynamic and others. I use mine with Senn' HD650 and Beyer' DT990.
I will ship within one business days of receiving cleared PayPal payment, excluding weekends and USPS holidays.
