I have the above phonostage, I noticed a fluttering sound through the speakers, so swapped the 6SN7 output valves.
I then lost a channel(after a couple of weeks) I put the original valves back in, all fine for a few days, lost a channel, swapped the output valves, sound was very low but in both speakers!!!!!

Any ideas???

Thank you
