I know this is an old video. but I am hoping to get some help. I am building a small single ended (champ) amp. has horrible motorboating! and as I turn the volume pot it sounds like a frequency generator and the frequency changes! I have checked my circuit over and over again but can't find the issue. Its a 6V6GT bias current is 25mA
great video the best and most easily explained motor boating
