The patent cited shows essentially the circuit of the X600. Many alterations
have occurred since those days, so you don't want to be relying on that
particular diagram.

Nelson,
Any hints on the B4 alterations. My proposed cheap clone apparently is getting further from the truth.

Thanks Mr. Pass. To me, Ultra-Symmetry [TM] says for every one polarity device there is its complementary. F5 fits this definition. And every F5 [in this model] has an identical twin be fed with out of phase twin input signals.
Best regards.

suppose you have a 4-quadrant output stage in the top floor, consisting of 2 Push-Pull OS's, makes 4 banks of output devices.

The Massive current sources are in the lower section, 2 banks of power devices.
Each of these is in parallel with 1 bank of OS devices in the top, to provide the SE current.
Which is in Short Hick's how the "regular" models are layed out.

Now, if these are set-up as constant current sources, they do not require an (audio) signal from the UGS6 board.
One side of the current source is connected to a rail, which is in the bottom section, the other connection is with the output in the top case.

Bottomline would be that the 50-50 split of the electrolytic cap banks is merely physically motivated, not enough room in a single case.
Mains enters in the bottom case, to the toroidal and the rectifiers, then out goes to the 1st lytic banks, and through the umbilical to juice the other six-pack (Xs-150).

Additional connectors in the umbilical would be for the ground connection between the top and bottom cap-banks, plus the 2 links from the L/R top outputs to the current sources downstairs.
Makes a 5-wire total, and Zero need for a Heavily shielded coaxial inside.

With an 8-wire cable :
- 2 in parallel for the Positive rail
- 2 in parallel for the Negative rail
- 2 in parallel for power Ground
- 1 for the Left current source connection *
- 1 for the Right current source connection *

* = less current

xformers ?

who need stinkin' buzzin' xformers ?

direct mains connection is for fearless Amp Bui/ahem/ers

so - that'sthe way - XS is , in fact , Circlotron , with cascodes in OS

jacco vermeulen. We are thinking about Xs, and will understand this puzzle. The objective is to understand this state of the art/science which Mr. Pass believes as expressed by viable schematics, measurements, etc.
  • What is the simplest schematic which describes Xs. Let us ignore for the time being cascoding, parallel devices etc. Let's nail down this schematic first. We know that it uses a constant and not a modulated current source in the output stage. A modulated current source maybe the next generation Xs.
  • What is Ultra Symmetry? Two neutrons or two stable atoms are Ultra Symmetric. Each similar pair is an exact 3-D mirror-image [twins]. It take two identical entities [at least] to express ultra symmetry. Others may have other examples of it.
Best regards

Cups too full. Step away for a while and listen to some good musak, preferably with transformers.

Ultra-Symmetry is just a trademark. I don't currently have a product described
as this.
