Title: Morphing Triode/Pentode Power Stage - is it crazy or feasible ???
Post by: kagliostro on March 03, 2011, 01:27:36 pm

As from Merlin's preamp book there is a way to obtain a triode/pentode morphing effect in little pentodes used in preamps

but is that feasible in the power stage ??  :rolleyes:

is this idea merely stupid ?

May be in the Power Section this way is more adequate

still not convinced it is feasible  :rolleyes:

This is how I interpret Merlin's Morph control for PP output. The pot could be dual-ganged in such a way that both gangs go to ground in the same direction
