Re: {Collins} KWM-2A cooling

Here is how I cool my KWM-2. The fan is a 12v unit from a computer power supply. The circuit board is a voltage doubler that is fed from the 6.3 vac from the 6.3vac phono socket on the rear of the KWM-2. 

The fan slips in  between the final cage and the exciter tuning mechanism. No modification to the rig.

	Having a small fan on the radio would probably make me feel better. I 
am not used to having electronics that generate heat, except for the CPUs.
	Thank you all, your advice is very much appreciated!
