    Schematic For Echostar AD3000ip Power Supply

    Hi Llew, No, they are not bifilar wound, and to achieve such a high value, there are many turns of very fine wire. So, we will have to see how the one I have fitted behaves in use.

    Thank you, Llew, for the resistor value. Yes, it gets quite hot, not surprising with almost 200v AC across it. Luckily, I have several 15k WW resistors of Painton make, from when I worked for them over 40 years ago. They are rejects for appearance, but electrically sound. They are 5w glazed...

    Schematic For Echostar AD3000ip Power Supply

    Thanks, Llew, for the excellent circuit diagram. My receiver has suffered failure of D16 and D17, which are easy to deal with - though procuring relacements might not be easy. Cricklewood has P6KE180A which I will need to check to see if it is a suitable replacement. However, the 'hot spot' you...
