Xiangsheng 708B tube headphone amp

Description

this is one cool unit. a lot of headphone amps aren't able to drive the power
hungry ones. this one is LOUD and on all my phones the volume control is
not quite at noon.
I wound up spending mucho dinero on an electrostatic headphones
driven by a large tube amp - it's the only way my tired old ears can
hear the upper trebles.
not tried this but can also be used as a line amp.
Back of unit says 220v,
this has been rewired for 110V
USA use.
you will notice the black shrink wrap on the yellow wire.
unless there's a voltage selector switch for your country, they are
all wired for home country use and you will have to change it yourself.
this will be double boxed and will include an adapter for those tiny little
plugs modern 'phones use.
no returns
thanks for looking
