thank you nr12 ;

in other words - google is your friend , especially when you use that switch on brain for something else , not just for off

( he is my Jacco , but please don't tell him that ; he's already vain enough )

Buzz - I gave up , trying to figure your Q.

will wait for next one

Saw the B4 thing checking out demo models on Lowther America. Thouhht you migt have an idea of what the change might be. Other than adding varaible Q of filter, not sure what could change. Thinking perhaps buffer type or different arrangemment of filter, non saleen.

but my confusion is completed/topped , when you gave link to FLARED PORTS THREAD HERE!! (I'm not shouting )

gimme correct link

[buzzforb]

Sorry. To many ADHD bits in one post. I told ya bout flare thing the other day in regards to mjk cabiney we have spoken about. I am on Nook, so cant post links. Cant copy and paste. Stupid Nook.

I'll wait , no worries

The four massive banks of output devices used in the X and XA series became six massive banks, with the bias current provided by the constant current sources increased by a factor of ten. This expanded the
single-ended power range by a factor of 100.




Dear people. Fig.1 of US 5376899 is an approximate schematic of the X and XA Super-Symmetry [TM] amplifiers. Actual schematics [per buzzforb] have not been published, and are not essential to analyze them and Xs. Assume that the attached Fig. 1 is what we are speculating about. It keeps this thread alive; despite it not a diy; but a commercial entity. But; we can birth a paper baby diy out of it.

• The power output ports center at common/ground voltage. Mr. Pass calls these outputs "live", and will drive any loudpeaker safely.
• The amplifying devices of the output stage are banks of P-MOSFETs # 30 and # 31.
• The constant current load to the output stage P-MOSFETs are # 34 and # 35.
• Current source # 25 is equal to #27 [very small for the front end] and # 35 [huge].
• Current source # 24 is equal to # 26 [very small for the front end] and # 34 [huge].
• And there is a small amount of loop feedback
• I count 7 wires for/in the Speakon. V+, V-, Signal ground, # 28, and # 29, CCS+ [for OUT+], and CCS- [ for OUT-]. I'll add a bonus 8th Star ground wire for the huge caps in both enclosures?
• That is a custom-made Speakon cord. Twisted [signal balanced] pairs with optional shielding to minimize crosstalk; per jacco's earlier concern.

Actually, each of the 4 Figures in the patent fits Xs, and power MOSFETs of both polarities are used. I'll post a functional schematic for a baby power diy using Fig. 2. The key is to have it in 2 boxes to get the simulation right.

SUSY is beaten almost to death ( even if that tiny difference comprised in "almost" is very important ) , but SUSY is damn different from Ultrasymmetric

even if both can be made with UGS , but connected differently

catch22 is that Pa himself said somewhere in the past something anegdoticaly in character - in time of patenting SUSY he wasn't aware of all things necessary for SUSY.... or better put - all things not necessary for SUSY

whatever - one thing is sure - XS aren't SUSY (except in that tiny amount of overall feedback , mentioned in OM)
