[QUOTE="SteViL666, post: 32732, member: 1760"] Yeah exactly! I ordered another EH 12AT7 just like the one the amp came with. The 12AT7 tube I replaced it with was an EH 12 AT7WT...it wasn't exactly the same type. I think that's why the volume got drained out. I will see when the new one I bought arrives- the same as the original Electro Harmonix 12AT7. If THAT doesn't help, then maybe the 3 tungsol12aX7's were bad. That is why I ask- Do you have to re-bias the amp to change the AT7?!? Or what? Anymore insight is definitely appreciated!!!!!!!!!!!!!!! RANDALL KICKS BALLS!!!!!!!!!! :evil: [/QUOTE]
