I just got a C-J CT 5 preamp which uses that tube. It's my first tubed equipment. I will order from C-J when I need new tubes. Thanks everyone.
popping sound with new 6922 tube
I am new in the tube world. I just replaced Siemens 6922 tube with Phillips. When I turn the preamp up for the first time in the morning, I get a popping sound (probably from tube) after a couple of seconds. A noise is delivered to speakers, too. Is it ok? Will it disappear as the tubes age? Or should I get a different pair? Thanks for your help.
