I have run the 22ØV fans on one of my TR-7 rigs and PS-7 power supplies for years...Not to mention the use of larger 22ØV fans on local repeater P.A. units.
The fans will run at a slower speed than rated...But will move a sufficient amount of air.

You can also use a 12V fan, mounting holes are standard
dimension so lots of fans will fit.
I found a 12V fan from an old computer PS that had
the same dimensions as the FA-7. Also with a 12V fan it´s
easy to speed controll it to get the noise down.
Since I don´t have the PS-7 PSU it was crummy to use the
FA-7 110V unit when there isn´t any 110V available, now
my old FA-7 is collecting dust in the junk box.

Hi Jeff,
You can pick up replacement fans at hamfests for three to five dollars. They are 110V units and fit perfecly. They run faster, pass more air and are a bit nosier than the Drake fans but a WHOLE LOT cheaper!!! I have seen the FA-7s go for as high as fifty dollars at auction. If you are not picky and just want cooling, the cheap fans are a real bargain. By the way, they also fit the end of the Drake DL 1000 dummy load.
