12UA7s are a big thing in a small tube. I am using mullards and the are a great improvement over the Chinese tubes that came with my McIntosh 2102 amp.
Time for new tubes.. which ones?
My TAD-150 preamp which has only 2 tubes stays on all the time, so every year I have to replace the tubes. This is my first time replacing them. Does anyone have an opinion as to what tube to use, or should I just use the same replacement ones from TAD? I would like to improve the sound if possible with new tubes. Thanks
