One day when I switched from CW to SSB mode on my Clipperton-L it blew the fuse
with a good bang. The switch picks between a tap and one side of the power
transformer secondary – tap being for CW. I forget but for SSB I think the
power supply supplies 2500V(+/-) and somewhere around 2000V(+/-) for CW.
Nothing obviously wrong that I could see with just the covers off. I replaced
the fuse and as soon as I turned the amp on it blew the fuse again. I searched
the web to see if someone had seen this problem before and had written about it
but I didn’t find anything. I have had the amp since it was new (1984?) but I
put a Harbach power supply board in it about 2 years ago. As a long shot I
thought I might ask here if anyone had seen a similar problem before I try to
troubleshoot this.
