This is understood sir. Please read the whole thread, I understand that there is a lot more than a switch and relay. I am not an amp builder, but have seen my share and had a few. The poster bought an amp that he is having issues with on ssb, amp bought on eBay, read above, any and all input is greatly appreciated as we are all here to learn. We have been PM about the issue he is having and he can't nail it down, amp works fine on am, has ssb delay potometer that goes from slow to fast delay, seller told him that he used it on ssb. He is not getting good reports with it on ssb.
