Cool Re: From the tiny island of Singapore....

Hi Peter,
The problem with mine is that the clean channel vol drops after about 5 min when I first switch on. Sometimes it goes back to normal after awhile (say 20 - 30 mins), sometimes it doesn't. Occasionally, it will be okay if I switch off and on again. The OD channel is also affected. Could it be the 12ax ?

It could be the tube. Try cleaning the tube socket with some contact cleaner - that could possibly be the entire problem. You could also try another 12ax7. Let me know if this helps...
