Some added info:The 12SC7 is the 12 volt version of the 6SC7. That tube is used in some older guitar amps. Incidentally, there is a 6SC7GT, but I don't believe there are any glass 12SC7s.
The 12SC7 is very similar to a 12SL7 (identical mu, but the 12SC7 has slightly higher plate resistance and slightly lower Gm), but the 'SC7 has a single cathode for both triodes in the envelope. Down the road if need be you can rewire the socket for a 12SL7.
The 'SCs tend to be a bit microphonic, but often a couple simple o-ring dampers is all that's needed to tame them.
RCAs are good, and inexpensive to boot. Sylvanias are decent too. that's based on feedback from a couple guys I sent tubes to that have Mapletree units too.
