Hi airtime - I read that you like the E80CF in your Sherwood 5000. You said you did the wire swap; was it merely changing the wires per the diagram, or did the resistors have to follow with the wires, if you know what I mean? I have a pair of NOS E80CF GE (Germany) coming in the mail. I have the requisite adapters, but I've read the E80CF is a bit taller than the rest, and I'd doubt the top will fit on. TIA!
