Happy holidays everyone! Just my luck this time of year, best time to show off Christmas LPs, my phone stage is acting up on my MX110... One of the channels has gotten really scratchy on the low end, and the two channels are starting to have different sonic qualities. I assume that I should try to roll the the 2 phono preamp tubes, V13 and V14 - 12AX7s, but I just wanted to check with you all before i bought them, or if you could offer any suggestions.
While I haven't swapped those two tubes, to see if the problems switch channels, I have verified that it is only on the phone stage, and the problem still exists when I hook another source up to the phono stage. So I am fairly confident its the phono preamp, but other ideas are more than welcome.
Thanks again everyone for your help!

What dou mean? Hook up another source to the phono stage? Yes swap phono tubes between channels is easy test.
Moved to the Analog Source forum.Yes, I changed the cart, and I also took the TT out and hooked up my phone to the phono stage. Obviously that won't sounds great, but I could still verify the problem.
