Thanks for your reply. I find the topic from Mario2005 http://www.diyaudio.com/forums/tubes-valves/83829-gu50-se-amplifier-class-6sn7-full-construction-details.htmlSearch on this forum returns 214 topics where GU-50 was mentioned.
Welcome to the club!
I just have the 6SN7 and GU50 tubes. Is the circuit no problem? Thanks
