Trazio sliku mog JLH i nadjoh ovu 807 SE sa ecc81 pre jedno 12 -13 godina a otislo negde dole na jug u nekoj razmeni.

v......o........l.........v.........o sto cudno pise BMW

Prihajali na spavanjac, snijega samo tako. Odavno nisam vozio sa ovoliko puno snijega a i zimazija je, ali na finalnoj destinanciji još hladnije i više snijega. Mala šetnja pre spavanja. Ima i neki muzej, pun instrumenata.

Now , if you take a look at Eagle front End schematic and Eagle Front End pcb screenshot (4th and 5th pics from top) said resistor positions are R3 and R53 , with R3 being position of our special interest : My taste dictate R53 being 1K , and R3 being 1K2 ; for anyone else’s taste , all what’s needed are few different resistor values and pincette/tweezers ; just power amp off , pull resistors out (gently,please) and push new one in (gently again , please). After that you can power amp on , or go out for beer and some talk , I don’t care

Now , few words about THD spectra shaping ; Papa taught us during the years several tricks how to imbalance that perfect Symmetry (ironic , isn’t it …… working principle of amp itself is called Supersymmetry/SUSY , while we are trying to spoil it . Anyway , we want some sugar , and we are getting that with 2nd harmonic above 3rd ; again – Papa’s Lectures – some people prefer that way (Tubelovers?) , while some people prefer dominance of 3rd (Sandworshippers?). Further – we can divide both of these groups by polarity of dominant harmonic- some prefer negative , some prefer positive. What can I do regarding that , except to find how (hardly first one knowing that) and then organize easiest way of doing it …….. If you take a look at LTSpice schematic of amp (third pic from top) , you can see two resistor positions circled in red. These resistors are path to modulation of Aleph CCS-es and their values are directly defining amount of that modulation , thus defining amount of Aleph CCS-es contribution in output signal . So , simple ; disclaimer – my goal is to invoke 2nd , and control it’s polarity and amount : -If these two resistors are same in value , there is greatest amount od symmetry , resulting in zilch 2rd ,dominant 3rd. -If we increase value of said resistor at side of positive output , there is increase of 2nd (and dominance over 3rd) , while our dear 2nd being negative phase, -If we increase value of said resistor at side of negative output , there is increase of 2nd (and dominance over 3rd) , while our dear 2nd being positive phase. That’s it . How it is organized in vivo ? I had idea to introduce sort of already know device among Greedy Boys , called -ZAP (Zen Amount Pot) , but later decided that would be impractical , and probably leading to constant play with , while forgetting enjoyment in music …. so I decided to use pin sockets/or whatever their name is , in said resistor positions , thus allowing easy change of resistors in situ , without involving soldering equipment etc.

po meni najbolji. naj seksi. naj smekerskiji. najlepsi od Volvoa - Amazon.

I forgot to write SuperSymmetry/SUSY anywhere on pcbs , but I didn’t forgot what’s more important: Did I said that they’re Gorgeously sounding ?

Few more pics , with lid on , and even with USB stick as size reference thingie: Some technical stuff: -Donuts : I ordered 900VA made on 1K2VA cores ; later -when actual winder guy itself contacted me to confirm few things , he said – do not worry , it’ll be 0.9T … they’re having static shield and outer tape shield . -Bridges are Big. -Each rail filter consisting of 90mF-0R11-90mF , resulting in 23V5dc. -Iq smidge above 7A , resulting in 100W/8R , 80W/4R , Winter blessing being in range of 360W per box. -Relative offset wandering some 25-30mV from stone cold to hysterically warm (top of sinks being 17C above ambient). -Absolute offset frozen around -350mV , right from powering up , all the way to hysterically warm. -Iq change around -4% , from stone cold to hysterically warm. -No power on thump , while power off thump is no more than small plop , even on my LC1B , they being sensitive on air flow induced by cat crossing next yard …… -Weight – smidge above 60kg. And yes – there is additional pair of drek binding posts at back , accepting any Remote Power On/Off voltage from 10 to 35Vdc, polarity irrelevant.

A ja Pipi. btw ručak.

kad porastem ......... bicu Ninja !!

Ovaj tip je Frankfurt (Germany) sa soundbarom. Mislim da je u BG sistem sa dva komada. Inače JBL 4355 x2 opušteno može da pokrije zapreminu manjeg bioskopa - centralni - kanal. Imaju maximum throw distance of 25m (82') Staviš dodatno sa strane pod uglovima (+4 4732) i pozadi (+1) - i full Dolby TrueHD (govno da ti se zaledi kad se pojačaju ) - bolje ozvučenje nema ni IMAX (pokrivaš dvoranu veličine Sava Centra) - zapravo su isti ti drajveri novije (serije) proizvodnje Zapravo nije mi jasno kako nikom do sada nije palo na pamet da napravi prvi privatni-državni bioskop koji ima Atmos Dolby TrueHD u Srbiji . Sve može DIY da se sastavi. Čak i Dolby TrueHD DAC Kupiš "jedino" (170K košta ali je bruka) laserski projektor koji je IMAX https://www.necdisplay.com/p/nc3540LS Jeftinije je od muzičkih fontana -a brat bratu eno im Kozara (otvorena 1911 godine) zjapi prazna kao smetlište u sred centra....

Čuo sam da je sistem kod nas u beogradu. Kažu da je u balansu, da mala soba i zid iza ne smetaju. Voleo bi da čujem to.

Pasivni hi-pass za OB, 250 hz, 12 db/oct, + korekcija 0.68 mH u paraleli sa 6.2 oma..

srecni putevi! ne zaboravi rezervne gace i nakurnjak!

Pa tako bi soundbar u stvari trebalo da izgleda... u nekoj osnovnoj varijanti[emoji57]

pravi diy...sam lik sve odradio. Svaka cast http://www.troelsgravesen.dk/Ill-4-Morten.htm

Naletelo jos stosta toga . . . ali me stra' da fotkam . . . . ima ovde puritanaca koje nervira kada ti se vidi sistem na slici ili bolje receno kada cesto slikas svoj audio sistem u kome svakodnevno uzivas. Jbga, mislim da mi je uspeo snimak ovako "iz ruke". Prosto ne smem ( jos uvek ) da turim u temu " Trenutno na gramofonu" . . . Btw, Grozni ispljuva ovaj LP samo tako. Te Oscar na zalasku, te salonsko-tezgaroska svirka . . . . a ja ovaj LP jurio k'o sumanut ono bas zbog nekih davnih vremena kada smo ovo slusali kao jednu od test ploca ( msm ono kada Ray Brown shapuce u puz od kontrabasa, pa Thipgenove metlice, pa . . . ) Zaljucak : 100 ljudi, 100 cudi . . . .
