I just had a very bad experience with Astron power supply people. I wanted to replace the main filter cap in my VS-50M power supply. I emailed them for availability of the 2200 MDF 35 volt screw terminal cap. They sent a photo of the wrong cap, wrong size, wrong values. I sent them the part number (C1) 220 mfd 35 volt for the VS_50M, they asked if i could give more information, I sent them a photo of the interior with a arrow pointing to the cap, they needed more info, I sent them the diagram with the part outlined. This is a large screw terminal computer grade cap, They sent me a photo of a 10,000 mfd, 25volt radial lead cap about the size of your little finger. after 10 or so emails i determined the were just screwing with me. Why would they do that ? By the way, if anyone could supply the right or even close cap i would greatly appreciate the help.
