110V version. First owner, perfect condition, used for <8 hours.
A great little tube headphone amp once you replace the factory tubes and very easy to mod. Plenty of information in these Head-Fi threads:

1 x Russian 6N3P-EV (replacement for the original Chinese 6N3)
2 x Dutch Amperex 6DJ8-ECC88 (replacement for the original Chinese 6N11's)
5 x JAN 5670W (alternative replacement for 6N11's; you need only two, so you'll have some spares)
All upgrade tubes are military grade NOS. Based on the prevailing oppionion on Head-Fi, these tubes are the best match for 708B.
The asking price is SOLD + actual shipping cost based on your location. The amp alone costs more than that. Honestly, I was very happy with this amp (but I guess that is what every seller says

). It's just that after barely using it during the two months since I got it I have to accept the fact that I don't have enough free time for the dedicated listening station.
