Posted na BIg DiyA, kao i obicno mrzi me da kucam opet
Finally, Plethora of Pinjatas, origin of P series of amps
These (P) being more or less derivatives of my recent M2 derivatives ........and you know them , so no need to go in detail
So, active FE instead of buffer+autoformer Fe; biasing mech being more or less same (current sense in rails), only - with help of current mirrors, being sorta flipped upside down, vs. previous optocoupler based one
even if optocoupler based biasing is moe than good, believe me, this one is even better ...... in anything you can remember to ask about
Iq and Offset stability is bespoke, in any domain I can think of - time, temperature, rails change ( mains fluctuation), no even slightest pops during Power On and Power Off
everything to embrace Square Law OS
(aha, this one being origin, even if its bigger brother - Babelfish XA252 been made first)
OK, straight MOS being real Plethora of Pinjatas ....... (is it Mini Babelfish XA252?)
SET P being then same pcb with twist - upper mosfet in Schade arrangement (is it Mini Babelfish XA252 SET ?)
pretty close to point where I can't even follow my self, go figure
'nuff babbling, some usual pics
schm is cumulative; down will post separate ones
