[Amps] sb200 fan question...

[jerome schatten]

I have acquired a nicely refurbished SB200 and all works fine.  The  original fan has been replaced with and FM200 Harbach and the noise (partly mechanical and partly rushing air) is driving me nutz.  I’m using it only on CW, but mostly I listen. Is there good reason to keep the fan going over long periods of listening?  I was thinking to key up the fan only during TX, or if things must be cooled while the tubes are in cutoff, reducing the fan speed during RX. 

Any advice appreciated!
Thanks,
