Sun Audio SV-6V6 SE amplifier

According to Sun Audio's web-site, the SV-6V6 SE amplifier uses two 6N7 (not 6SN7) tubes. Is it so or it is a mistake and it uses 6SN7 tubes? My friend is looking to buy a used SV 6V6 amplifier in excellent condition cheap but without tubes, hence my question.

Thanks in advance!
No,it's not a mistake.There is plenty of info on the net about this tube.I suggest your friend do a little research to find out just what he is getting into.Just a thought.Good luck.
Thank you! I will tell him.
