I have a HP8656A signal generator. Works fine for FM and AM. However, when using it to test a SSB receiver there is a pronounced "warble" in the tone and it is...
They all do that. The 8656A has a lot of close-in phase noise. Not clean enough for any SSB work that requires an extremely stable reference. -- john KE5FX...
I found similar problems with my 8656A. I replaced all electrolytic caps. I also replaced the osc. I believe it's a FET, try Sphere in B.C. they had some....

Pigtail style caps with shrink sleeving, tie wraps etc (NOT ELECTRICAL TAPE !) to hold them together, kind of a kludge...but effective Dave ... Dave NR1DX ...
