For those of you who want more drive and sustain from the front end along with an earlier breakup from the output section. These will not hurt your clean tone but as you dial in gain you will just get a bit more. A matched pair of JJ EL844's to reduce the output, two handpicked high gain ECC83S's for V1 and V2 with a high gain balanced ECC83S for the phase inverter in V3. More gain from the front end and earlier distortion from the power tubes!
