[Amps] 4CX250 bases (David Kirkby)

[David Lisney]

Hi, just to confirm that like another contributor the base in my wee CCS1 
amplifier is an "air system" one, I used a small brushless fan to cool the 
valve base area and to get a wee bit of airflow through the PA compartment, 
the fan is a 12v one run at reduced voltage, also helps to keep the 
stripline reasonably cool, it seems to warm up pretty well with circulating 
current!

The fan I have for next project is altogether different, just fired it up 
and launched papers everywhere....
