This is a low tech and improvised approach. Use a small, low CF/min muffin
Fan from a computer; put some rubber pads on it so that it will exhaust upward
and set the fan on top of the cabinet above the final tubes.

That is what I do. I use a 24VDC computer fan and run it at 12VDC. Effective
and quiet. Be sure to have it blow upward.

Mount a small 3 inch 12 volt fan on the back of the PA cage, the holes match up
without any modification to the cage. Take 12 ac from the filament supply
somewhere under the chassis and run it through a diode to a small electrolytic.
The size of the electrolytic will actually decide the fan
