  A Yamabe soliton is defined on arbitrary almost contact B-metric manifold,
which is obtained by a contact conformal transformation of the Reeb vector
field, its dual contact 1-form, the B-metric, and its associated B-metric. The
cases when the given manifold is cosymplectic or Sasaki-like are studied. In
this way, manifolds from one of the main classes of the studied manifolds are
obtained. The same class contains the conformally equivalent manifolds of
cosymplectic manifolds by the usual conformal transformation of the B-metric.
An explicit 5-dimensional example of a Lie group is given, which is
characterized in relation to the obtained results.
