Even though these tubes are relabeled Chinese tubes, I still find them to be very nice and above average quality. I would swear my Peavey Classic 30 sounds warmer and there’s more definition in the tone than before. I’ve compared them in this amp with JJ, Ruby, Tung Sol, and Sovtec. These TAD tubes are the best sounding to my ears, JJ’s and Ruby’s were the worst in my opinion.
