[TenTec] Fan kit for O2

[Bob McGraw K4TAX]

Peter et al:

I picked up a 12 VDC fan from a local hamfest, or perhaps on-line.   
Choose one about the size of the heat sink or a bit smaller.     For 
attaching the fan to the heat sink,  I used the type of plastic anchors  
for securing a screw into drywall. Choose a size that easily  but firmly 
pushes in the fins of the heat sink.  Then using screws that go through 
the corner holes in the fan and extending about 1/2"to 3/4" attached the 
fan to the plastic anchors.   The fan is positioned to blow air onto the 
heat sink.  Power it from the station supply or the 12 V acc source on 
the radio.  If the fan runs too fast or makes too much noise, insert 1 
or 2 diodes in series with the leads to the fan. Using this method one 
can easily remove the fan if needed and no modification to the radio are 
needed.
