lt cdr data said:hi Mike I think its complete, q208 is output biasing/vbe.
q216 is the pre driver, the collectors are obviously the voltage amplifiers
MikeB said:Hmm, i think it's not functional at all ?
The biasing in the outputstage is not defined at any point,
collectors from predrivers connected to base of drivers
without any resistor defining a voltage ?
Also, i can't see how the vbemultiplier should work ?
Is the schematic incomplete ?
