Hi all. This is my first post here, though I have received a lot of valuable information from this site.
I recapped my C-4 pre a while back and after words noticed some HF hash on the output at around 400kHz. I didn't look at it before the recap, so don't know if it is the result of the recap or if it was there before. It seems to be all over the place, though the 30 volt rails look clean IIRC.
I'm not sure how to about troubleshooting this problem. Any ideas anyone?
