The amplifier is in excellent condition cosmetically and
operationally and is available for pickup in the Los Angeles area
or for shipping in the continental USA only since it is very heavy
and the tubes need to be packed separately. It comes with a
protective metal cover on the top.
The tube design may be very obvious to those who are Marantz
fans as their older similar unit typically sells for $5,000 on
eBay. This brand new unit is significantly less.
It uses EL34 tubes for the unit.
