When you say, "it looked like someone put a campfire on the 50A5 socket," do you mean that the socket has some signs of scorching? That can cause problems right there because the burnt areas can act as resistances and screw up the circuit. Best to replace and cooked sockets. If you are receiving stations the IF transformers may be OK. Have you done an alignment on the set yet? Re-tuned the IF transformers so they are peaked? Done the rest of the alignment? When you replace condensers and resistors in a set it can change things and require a full alignment. If, after these thing are taken care of the performance is still unacceptable, then you may have deeper problems, but I would start with those.
