[QUOTE="Mars, post: 711015, member: 817"] I have 6 dual triodes available for the combination of phono stage (uses 3 dual triodes) and preamp/driver circuit for the KT88's. I am considering using a 6SL7 dual triode shared between channels L&R driving a 6N7 phase splitter. That is 3 tubes and should have enough gain to drive the KT88 grids into clipping. Something vaguely like this: [IMG]http://www.tube-amps.net/images/KT88_PP_01/KT88_Schematic.jpg[/IMG] Input stage one half of 6SL7 and Phase Splitter 6N7. The rest would probably be similar. I am considering dual chokes and dual power supplies to separate the current demands of 4 x KT88's running at max. Has anybody used center tapped chokes to split HT. This scenario does promise smaller core size for effective induction. [/QUOTE]
