Add a dirty signal anywhere in between will make for a dirty amplified signal. Most likely class c amps.
Any way to open the amps and get a couple of photos of the inside, or at least a photo of the amps in question. Again I will say this, I would not use a class c bias amp as the signal is dirty, class b is normally the minimum that works on ssb, class a/b being even better. Some of the older palomar amps had a/b stamped on them but I don't know if they were real class a/b amps. If you have and bought the fatboy amp new, send it back and ask for the amp to have the bias properly set for ssb use. I use a magnaforce 350hd 2 transistor amp that was made by xforce a while back. It's a class b bias amp. Works well for ssb use and in have been told several times it sounds like a rolling base station. Go anything below class b and they sound like garbage on ssb. Send that fat boy amp back and ask for something that will work on ssb or send the amp to a good amp builder and let him properly bias the amp for at least class b operation, a/b would even be better, you may not see the same watts as the class c amp, but the output signal is cleaner. And like I said clean in equals clean out. Hope this helps and you get everything straightened out. God bless.
