Not my 374A! Hmmmm...it's possible they changed something during the
multi-year sales cycle of this product, but the "374" meant "3 x 8874" and
used 3 tubes -- at least mine does. They also had a "274" which was "2 x
8874" and used two tubes. Mine exhausts out the rear, exclusively. There's
no holes in the top, at all.
