[QUOTE=">COR<, post: 242010, member: 176572"] No appologies needed m8, just an thanks to you for your excellent work on the reciever :) Think it still does an very good job, not planning on parting with the reciever yet, running my actuator fine with the 1.1 Triax dish from 50 east to 50 west. I put the fan on top of the PSU then, took out an section of the top cabinet and blow the air in, cleaning the reciever once an year of dust. Inside stays absolutely cold, reduced the rpm's of the van with an small resistor in the + lead feeding it from the +12 volt line on the back. The only design flaw they made was to block the airflow from the underside of the cabinet to the top with the PCB. This way they made the reciever no airflow could be possible from the underside to the top. This causes the PSU to heat up too hot, caps loosing their fluid and break down, as well some makes of the memory chip wich were an bad batch to go prematurely. The cooling with fan and heatsinks solves those problems. Use ballbearing fan, these last the longest. Cor [/QUOTE]
