Hi Folks,
    Just wondered if anyone knows the best modification to use to either quieten or eradicate the extremely noisey cooling fans on the FT-847.

Picked up a used FT-847 and the noise is like thunder.

Saw a number of mods on the net from the addition of a Thermostatic Fan Speed Controller circuit/ Fan replacement /zener diode in series with the power lead / ganging the rear fan with the circuitry that controls the internal fan/disconnecting the rear fan !! and someone else suggests muffling the fan with some foam !!

Any ideas are welcome please.

Thanks,
Don EI6IL

A smoking section in a restaurant makes as much sense as a peeing section in a swimming pool.
