  We study the transport through a quantum dot coupled to two leads by
single-mode point contacts. The linear conductance is calculated analytically
as a function of a gate voltage and temperature T in the case when transmission
coefficients of the contacts are close to unity. As a function of the gate
voltage, the conductance shows Coulomb blockade oscillations. At low
temperatures, the off-resonance conductance vanishes as T^2, in agreement with
the theory of inelastic co-tunneling. Near a resonance, the low-energy physics
is governed by a multi-channel Kondo fixed point.
