Floating ground dual class amplification A + B/C/D/etc...

Post by roberto »

Hi,

another idea that came to my mind while reading this:
www.thatraymond.com/downloads/solidstat ... a_v1.0.pdf
(see page 112)

Is the possibility to have a floating ground tube power amp working in class A amp plus a class B/C/whatever with high efficiency and high power. The secondary of the tube amp (and the iron as well I would say) has to be able to supply the needed current for the full swing of voltage of the D class amp + the A class tube amp.

The C/D/whatever amp, together with the preamp, will be grounded, while the PA & OT will not, but will use the floating ground controllet by the C/D/blabla.

Do you see any reason why this could not work as planned?
