Ron;
Yes a semi-remote cut-off 6SG7 would probably be best choice. What that says is that the tube will still exhibit some gain even if AGC is telling it to back off on gain. It makes for a slightly more sensitive receiver than the other choice. I think the only time you might want a remote cut-off type would be if you were combating a really strong BC band local signal. My son-in-law's dad lives in McPherson, KS and there is not a problem with really strong signals right there.
I just finished mounting a ceramic top-side saddle mount Octal socket which neatly covers the Loctal socket hole with room to spare. Next I will order a 6SG7 to install. I had one old Silvertone and one old Admiral AM AC/DC chassis that might have had a socket I could have used, but installing a bright shiny new socket looks better. I misplaced those chassis anyway. Next I need to check the pin-outs for the 6SG7, although I think they are the same as the 7H7.
