muel Posted April 26, 2016 Share Posted April 26, 2016 I'm still on my first pair. They are the end of any 12au7 discussion in my experience! It is interesting how little information you can find about these. A well kept secret. Quote Link to comment Share on other sites More sharing options...
paul79 Posted April 26, 2016 Share Posted April 26, 2016 Secret because there just aren't any I am still using my first pair also. Test like the day I plopped them in the amps almost 8 years ago. Quote Link to comment Share on other sites More sharing options...
