This is a dumb question, but is there any chance the 6A8 and 6K7 coulda got interchanged?

I never touched any of the tubes when I was recapping this radio or when I undid the B- wiring from the negative leg of the volume control.
The only time I touched the tubes was to test them in my tube tester to make sure there weren't any dead ones, but I disconnected them one at a time so that there wasn't a chance for them to be put into the wrong socket.
I don't have any spare 6A8 tubes unfortunatly, and the weird thing is that the original owner of this radio replaced the original 6A8G tube with a metal 6A8 tube so because of that they ended up throwing out the original tube shield that went in that spot and unfortunately the metal 6A8 tube doesn't fit into the tube socket very tightly like the original 6A8G did so I have a feeling that the replacement 6A8 tube may not be making very good contact with the tube socket because the tube pins don't seat all the way into the tube socket.
I also checked the 7G7 tube and the pins looked kind of crusty looking but I wasn't sure if that would of caused the issue I was having or not (I know Loctal tubes are notorius for making bad contact between the tube pins and the socket).
