[Amps] What blower?

[N7HIY]

Hi Mike,

put in a blower that exceeds the tube's requirement by at least 10% and then 
speed control down for needed cooling at duty cycle in use, far more 
adaptive, can be used for contest digital modes and has higher resale 
value...can even put in thermostat controlled speed control for even less 
operating noise
