Time to retube the XXX head, which 6L6's?

[tweed]

Going to order some tubes from Doug'sTubes for my XXX, need a few 12ax7's and it's probably time to redo the power tubes as well. I have no idea which quad to get for this amp.

Ruby Winged "C" 6L6GC
TAD 6L6GC-STR
Svetlana 6L6GC
SED 6L6GC

I would go with the regular Svetlana's. I have the EL34 versions in my JSX and they are great.
