    I'm getting 168 volts at 2sk3520 but no voltage after the x-former. I replaced a bloated 1000mf at 10volts in the secondary and thought the unit would fire up but it didn't. Any help would be appreciated. Thanx.

    A schematic diagram of the power supply will help. Thanx.

    Should have swapped the receiver through DISH before you tore into it. Now you could try searching on ebay for a nonworking "for parts only" leased receiver that is being sold cheaply. Use that as a source of parts until you find the actual bad parts that you need.

    Or just get a grasp a concept of switching supply and you'll be 'independent' of particular implementation.
