Three 12AX7 and One EL34 guitar amp? Need a schematic to build
Question:
Hi everyone, I want to build a guitar amp with modern gain at a lower volume and have the amp cranked. Do you know where I can find a schematic for an amp with: 12AX7 x 3 EL34 or E34L x 1 Just simple tone controls: Gain, Bass, Treble, Mid, Master Volume Cheers Tim

Preamp and output stages don’t have to be on one single schematics. You can get yourself a single-ended EL34 power amp schematics on one side and a 2*12AX7 preamp schematics on the other that would suit your needs. Then you simply plug them together. It’s not a mistype to write 2*12AX7 cause the power amp requires a 12AX7 for the dephasing stage. Or you can throw in another 12ax7 ! – Hide quoted text — Show quoted text -> Hi everyone, > I want to build a guitar amp with modern gain at a lower volume and > have the amp cranked. > Do you know where I can find a schematic for an amp with: > 12AX7 x 3 > EL34 or E34L x 1 > Just simple tone controls: > Gain, Bass, Treble, Mid, Master Volume > Cheers > Tim

Try the AX84 site (www.ax84.com). They have several single ended amp designs, and although the EL34 is not the primary tube used in any of them, I believe that there were variations presented that DID include the EL34. – Hide quoted text — Show quoted text – > Hi everyone, > I want to build a guitar amp with modern gain at a lower volume and > have the amp cranked. > Do you know where I can find a schematic for an amp with: > 12AX7 x 3 > EL34 or E34L x 1 > Just simple tone controls: > Gain, Bass, Treble, Mid, Master Volume > Cheers > Tim

…as long as you can get the plate voltages in order. – Hide quoted text — Show quoted text -> It’s not a mistype to write 2*12AX7 cause the power amp requires a 12AX7 for > the dephasing stage.
