I use 2 hf rigs,2 mobile 2 meter radios and many lights on tuners,meters,etc. I did cut the positive wire under the cover and soldered a resistor in line to run the fan at 60%.this quietened the fan a lot and makes it more appealing. overall I cannot complain for a 8 dollar part!Įarlier 5-star review posted by VE7REN on Īfter runnin this power supply now for a couple weeks,im happy. Astron should address the crappy fan they use. I love the output on this unit,and the fan is much better than the stock. it worked,but now with the new fan.it is very quiet. originally I had added a resistor to the orig fan,as you can read in my previous reviews below. Ive owned this supply since 2015,and have now replaced the original fan with a stealth brand for 8 dollars from amazon. more energy efficient and less footprint and money then the linear supply. when the fan comes on the samlex,it is auditable,as many fan cooled supplies are! regardless of the negative reviews this supply has gotten,ide buy again. it compares to my samlex 1235 for fan loudness. some rfi spikes can be seen on band scope,only on 80 meter.noticable from 3650-3860 using the icom 7300,no other bands effected. this supply has never failed me, runs almost silent sits ontop my shack shelf. Solid performer,BUT you have to do the fan replacementĥ year update-2020.
