Ampeg SVT 2 Pro Fan Direction ?

[Xandrell]

Does the fan direction go up or down? There are no vents on the top or bottom panel, just the side. Are there air channels below the fan between the bottom panel? Thanks

Look at the fan blade design. Appears to blow down, this would prevent excessive heat build up in the PCBs and exhaust would be from around tube openings in the chassis deck.

Thoughtfull design actually. Only thing missing from the design is needed filtering.
