Friends hi-fi system not very good, what do you do or say?
I would simply say to my friend that he/she shall audition the audio system from his/her friends to realize what good sound should be.  
???What's The LEAST Expensive "End Game"Amplifier You've Ever Heard???
I cloned the Mission 776 preamp. I found it sound so good indeed. I don't have chance audition the Mission 777 power amp.  Maybe you should try this Mission amps if you have chance.

Hi Alex, I would prefer using those NOS 6V6's. They are available from Ebay and https://www.usaudiomart.com/.

845 Tube Sockets.....Bayonet vs plug in types?
I prefer the good old Bayonet socket. It is much for robust and secure. I used them in my 845 single-ended power amp.    Johnny
