[QUOTE="handsome, post: 304324, member: 772"] very interesting read indeed. ironically the biggest modification to the Dynaco power amps is of course the removal of the 6AN8 voltage gain/phase splitter. The split load phase splitter is (in my humble opinion of course) the best phase splitter having very low output impedance (when facing a matched load on each phase) but unfortunately needs tons of HT in order to accommodate both phases' voltage swing requirements - sometimes more than the output stage HT in more adventurous designs. Ampdog is correct in pointing out that paralleling many EL84s is an ideal way to get both higher power and sidestep the HT issue and EL84s are rather cheap..... [/QUOTE]
