thanks guys, I am going to get some new pre amp tubes today, Im posistive the stocks were still installed when i got it, hope that will fix my problem. I thaught it might have been dirty pots or something so i did take the back off and look at things, everything looked normal at an uneducated glance. I didnt see any burn marks....so i dont think or know if a resister is blown or what. Yeah my amp has 3 12ax7 preamp tubes, im not sure what a phase inverter tube is. If i do want to spend some more money to get some new power tubes, should i take it in to get those replaced or can i do those myself too. I very interested in all input and knowledge you guys have for me.
Thanks again
