I bought a cryod Mullard 12au7 nos tube from Kevin at Upscale Audio. I noticed the difference as soon as I inserted the tube as it was quite dramatic. I received it earlier today. The Mullard seems to have done the trick. There is now the desired richness in the midrange and I am quite pleased with the results. Thank you all for the help.
Changing Preamp tubes on a Cronus Magnum?
In an earlier thread, I mentioned getting my Cronus Magnum on Friday. The amp was well broken in when I got it and I have put at least 24 hours on it since receiving it Friday morning.
I want to ripen the midbass/lower midrange a bit and from what I understand, it's the center 12au7 tube that makes the most difference. What would be a quiet tube that will ripen the sound a bit? Thank you.
