Is the configuration of the output similar to the s.e.x. amp -- i.e. - grounded cathode and We split rail bias, or more like a standard cathode bias with bypass cap?
I'm moving back to the standard cathode bias arrangement.
The WE arrangement came aboutwith the SEX amp because we wanted to try an autoformer and use it with headphones, so the entire winding, primary and secondary, had to be at DC ground for safety. The WE arrangement allows for that, at the price of requiring two floating high-voltage power supplies. Then when we were developing Paramour II (monoblocks, hence two power supplies already) we realized the same arrangement would allow us to return the signal current loop to the cathode so it does not go through the cathode bypass capacitor. We could not do that before because the stock output transformer is not rated for any DC voltage.
Now that we have an in-house output transformer of better quality and rated for an appropriate DC voltage on the primary, I am ready to give up the WE arrangement and its complications.
