Bill - Let me know how you make out with this. Infortunately I don't have any spare connectors. I also came up with only one spare 812 that I needed for my Stancor 110CM cathode modded rig. It uses a pair of 6V6's to cathode mod a single 812A. I checked the tube in it hoping I could give you my spare. Unfortunately it's very weak. Regards, Joe N3IBX
