Please forgive my ignorance! Is the 6SJ7 with the use of a suitable adapter replaceable with the 6J7 • EF37 • ME1400 and do you think it would be worth it?  I do realize the last question is a tough one - just wanna hear about your own experience.
 
Short answer - maybe, depending on the circuit.

To learn more, download one or more of the RCA Receiving Tube Manuals from this site: http://www.tubebooks.org/tube_data.htm

I looked at my paper copy of RC-21 and there are several differences between the two tubes.  Again, depending on the circuit they may or may not matter.  You can always just try it - they are close enough that you are not likely to hurt anything.
