The 12SC7 is a 12SL7GT with a "special shield" to reduce hum according to tube data documentation. A 12SL7GT could be used as a direct repalcement. I've never needed a special shield when using 12 or 6SL7GT's in an audio circuit. 

GT=glass tube.

Should be. 

Just tried the tung sol JAN 12SL7GT.  Dont like them. I have to twist the volume up quite a bit to hear music.   JAN 12SL7 sound pretty good, these are a metal can style.  I just need to find a real good pair.
