i knew the receiver was working because ewtn was ok but no response from the controller. it had died in the past and i had replaced several 1000mf/16v capacitors with temporary fixes. in the meantime got 1000mf/25v to replace the bad ones. one of the fixes was 470mf/16v so i replaced that one. it was the right one because i fired up the receiver and it worked. if anyone has an open box or solomend that is failed and wants to part with it, i would be interested in it. i spent 40 years in tech work for the navy and at&t and school districts so playing with electronic is fun. charlie
