What is confusing to me is why do I not hear the sig gen tone when connected to the 6A8 but I hear it loud and clear when connected to the 6k7. Also even when I watch the meter if I connect to the 6A8, I still not get a meter reponse while adjusting 33S and 33P which tells me that IF ransformer is not working.
