Super Sanken Final Stage "Tauro"
Hi my last project is an hybrid with 2SA1215 and 2SC2922 drived from a copule of comlementary hexfets IRFP240/9240 (after evaluation will be IRFD110 & C) the output is with big capacitors (20.000uF) just to leave DC (this balanced solution don't create emphasys on music) in this particular design i have put two bipolar devices instead single one (in AB bias) because need Class A sound without bridge there is an "auto-biasing" between a copule of complementary transistor in this configuration, so need just a resistor base to base ----------> I don't know if works <--------------------- is a project until this WE this double bipolar ( renamed Tripolar ) is a PNP+NPN with common collector so is like a self-biasing device that works (may be) in phase as a variable resistor ( signal modulate value ) input satage with common source split phase in two opposite rail without feedback and mirror Regards Stee has attached |
