Please don't put the 6h30 in your preamp! There are plenty of NOS and new 12au7 options you can try and they are quite cheap. You can do a lot better than EH.
Preamp issue?
My Cary Slp3 started to act up.
Few days ago I noticed something was off, but didn't have the time to listen critically..... yesterday it was even more pronounced but still not obvious...I realized that right channel is a tiny bit lower level than the left channel.
I eliminated all obvious issues, like bad connections, balance knob turned, etc...
I don't have spare tubes, and before I start opening the chassis and switching the tubes, just want to make sure this is even a possibility.
Thanks
