Hadn't noticed this earlier but I guess I should make a comment about this fantastic headphone amplifier. This is one of the two EHHA rev. A amps that I made about a couple of years back.The amp has functioned flawlessly since then and I only sold it when I completed my Beta22 amplifier recently.
Salient features :
Fully dual mono construction with two 30VA toroidal transformers and separate power supply for each channel
Schottky rectified DC heater supply
Vishay electrolytic capacitors
NP0 ceramic capacitors
Kiwame (Koa) output resistors,rest MFR 1%
All transistors hand matched within 5%
Uses original japanese Toshiba 2SA1145/2SC2705 small signal transistors (Now out of production and almost impossible to find)
Alps RK27 'blue velvet' potentiometer with shunt mod
Neutrik connectors

IMHO, no headamp even comes close to the EHHA in terms of performance at this price range.

@ Oyster : which tubes are you providing with this ( the two pairs I provided are alone worth atleast $150). Good luck with your sale.
