eric	Re: 12ax7 parallel SE Thanks for the explanation, Now if you were to use five individual 12ax7's all paralleled, would you be able to do the 125k/5=25 and have a load suitable for the reverb transformer? Also can you point me to some data sheets on the 12a_7 tubes, my favorite site went down and cant get them anymore. One last thing, what about mixing 12AT7's with 12AX7's all in parrallel to get the resistance down BTW what exactly is the calculation that you are using to determine the total resistance's is it just like a parralleled resistor? Where can i find information about how much voltage ect to apply to the tubes, unfortunately all i have done in the past is copy schematics, but i want to actually understand and hence this project. thanks
