Hello Norm
There's a Teflon chimney,(not shown),
from the tube's cooler up to the top
cover. The goal was low back pressure
plus tank component cooling, seems to
work FB.
Air inlets are placed at various places
in the cabinet floor to cool the
transformer, PSU and control circuits.
The cabinet stays cool to the touch.

Paul,
I see you are using a pressurized
compartment and no chimney on the
YC-156. I dont know what your design
power level is but it would seem to
me that you have reduced the tubes
capability appreciably. With 300 watts
of filament power to dissipate you might
not have much left for plate
dissipation. What power level did you
expect
from your design??
