decije bolan zezam se - moze to korektno da radi, kao sto ovo i radi korektno Nele je krenuo sa ovom serijom pojacivaca- jos onomad od ACA - na nacin koji je neverovatno uspesan po pitanju masovnosti i popularizacije zahvaljujuci tome sto se koriste cigla ispravljaci nema komplikacija sa ozicavanjem mreznog napona, maltene pola mehanike je izbegnuto, sastavi ga i pionir od 12godinica uz pomoc nekog iskusnijeg i sto je naveci fazon i kvalitet - biranim designe-om se dobija da to svira neverovatno dobro za ulozene novce i ulozen trud - trci u krug oko ne znam kolko skupo placenih komercijalnih proizvoda msm, daleko bilo da je to my cup of tea, ali cilj misije je itekako postignut ovaj ampic svira ko avijon ....... nije dzaba Lottery Amp

Ma to je kao naturpijan sleeper na cesti. Svi vide kad je nešto brzo, ali kad te odere Volvo 744 karavan sa 700 konja boje više trule nego višnja i sa hrđavim čeličnim felgama vilica se sama otvara i pada na pod taman da si u AMG-u. Naravno da je super kad se može napraviti i da lijepo izgleda. Zezamo se malo na vlastiti račun. EDIT: Off topic prebačen iz Ove teme

Ne brigaj Shonne, u pitanju je zavist! Аристотел је дефинисао завист као бол при погледу на туђу срећу, подстакнуту од „оних који имају оно што би требало да ми имамо" - kraj citata

Rest of pics Observe - there are some trick which can make your life easier: -Cone head temporary screws ( aligning, no scratches round holes) -align brackets with back side of heatsinks, no warping of back plate in that case headless screws for front plate; how to unscrew and orient bottom to mount washers and nuts and tighten them wiring done with one heatsink, bottom and back plate screwed together; then mounting second heatsink, soldering wires, then mounting front one or two pads are close to screw nuts; marked on pics; either use plastic washers or metric screws/nuts ( smaller than enclosed ones) or be brave as MZM - I did bend integral star washers, was stubborn to use Papahardware dunno - I did forgot something for sure , but you'll ask; it's not Rocket Science anyway there are probably few redundant pics, but - hey - web space is cheap nowadays

Amp No. 122, member tunasto here, @vinko on Baby DIyA Let's start with schematics - I like when schematics are present DIY SONY VFET pt2 shrinked.pdf

hvala @Leonardo ja ne mogu da se izborim sa ovi svajseri

Ja kad napravim vidi se da je domaćica iz familije najvećih umetnika Firence i Milana, a bogami i Zemuna. Gvožđane "fioke" i "tepsije" su za čuvanje šrafova i namakanje u nafti

Kad sadašnji printeri isprintaju dovoljno veliki printer za velike avijone...

Pa i Ikaro je nesto leteo, ali mu se istopio lepak. Mora da su sada sredili taj bug

Nema napajanje. Riješio je Teslinu zagonetku, ali neće zbog CIA-e da još priča o tome.

Facts -PSU 36Vdc -Iq one channel 1A76, second channel 1A8; was thinking to alter that to 1A6 by the Book, but who cares - more the merrier -Output node set by the Book - to 14Vdc -Ambient Temp 20degC -VFet Case 66degC -Mos Case 59degC -T Bar Temp at exact mid between two TO3 50degC -Heatsink Temp at outer side, between fins, exactly between M4 Allen head screws 44degC -1R5 at channel pcbs 99degC (Papa is FAB, no clearance) -3R3 at PSU pcb (ZM is Chicken, 2mm clearance) 88degC -JFets 44degC -Switcher case , placed on edge at bench 37degC -no noise, no hum -It sings; forgot to take a picture

Delay circ tweaking Again, self explanatory

Still on back side of amp Mean Well switcher PSU is of good quality, but I don't like flimsiness of DC connector, neither male nor female one Good ole 5-pin XLR is certainly better; I would like Calt Stecker being on cable, Heiss Stecker being on amp, but didn't had Heiss one ....... anyway , I did stay with original topology - Heiss Stecker on cable superblingy drill and edge reamer, no need to be overly precise, XLR is covering all I didn't even hop to my vertical drill, done it with hand-accu one useful tip for soldering pin-equipped connectors - always mary male one with female one - no bending of pins in plastic, due to heat

solving thermal issues; see pics, pretty much self-explanatory whoever did arrange with Modushop guys assembly with M3 screws is not having enough mileage with all things mechanical/thermal; not blaming a guy at all, I know that this wasn't operation made by professionals and outcome is still extraordinary that's exact reason why I'm posting this, to help Greedy Boyz in proper finishing and to feed my own OCD fact is -these 4pcs of M3 screws needed to be M4 and additional 2pcs of M4 are necessary only that way , with lapped T Bar, there is enough squeezing force at disposal to get rid of air gap between T Bar and heatsink

Dejanco32, nisi svestan koliko si u pravu. Većina vrlo važnih spojeva na avionima je lepljena i to drži samo tako! I bolje je što putnici ne znaju koliko ima tih lepljenih spojeva, ali ne baš Alu-samolepljivom trakom.

Ili jos bolje JBL xtreme. Tu vec mozes i da uzivas. Slusao i Bose Revolve ali mislim da je Xtreme bolji. Revolve dosta osetljiviji na pozicioniranje, kad uhvatis sweet spot takodje odlican.

DIY ide u neku kutiju bezveze, da se vidi iz aviona da je pravljeno, a ne ovako ...

Pa to nuklearni udar da izdrži, ako Rusi zakuvaju sarmata. Samo naspeš sitne sačme da dampiraš oko trafuljka

nista tvoja bolest nije u odnosu na onu glavnu

HELP ! pa DiamondLife, pa JJ Cale... GRAAAMOOOFON...!!!🍻 YEBO FLACOVE I YOUTUBE I ...Berzo, eve me ponovo, podhitno!

Sad me podseti na ovo.

Prije oho-ho godina sam iamo nekakav butik u svom gradiću. U vrijeme dok se nosio Big Star, Unlimited, Scotsh&Soda, Gas itd. Tako sam pred Božić napravio nekakvu nagradnu igru za kupce. Ovdje sam priznajem da sam namjestio prvu nagradu (zimsku jaknu od Scotsch&Soda) jednom dečku za kojeg znam da si nije mogao priuštiti da kupuje tu robu, ali je ipak silno bio želio hlaće, pa sam mu ih ranije dao po nabavnoj cijeni i na nekoliko rata bez čekova i slično. Nisam mu nikad ni rekao da sam namjestio izvlačenje koje išlo live na lokalnom radiu. Ostale nagrade su stvarno išle po sreći, ali sam htio njemu pomoći, tako sam u uvodnom razgovoru pred izvlačenje na radiu voditelju rekao "da je naših rođaka puno, a nagrada malo". Nije mi taj lik rođak. Čak ni prijatelj, ali mi se učinilo kao dobra šala pred izvlačenje nagrada.

ne mora da bude mobilan. ja bi najradije sa lampama, tipa 6080 - 6AS7G. ali, opet, sluske od 2K su zahtevne po pitanju teranja. u fazi sam trazenja sta i kako. a napraviti - za to se ne sekiram.

Sta vi znate,...ruzan uredjaj ne moze lepse da svira od onog koji je lepo napravljen 😁

Ja kad napravim vidi se da je domaćica.

Mean Well switcher od 36Vdc/150VA ladan msm taman za decicu - to sad moderno na Big Diya

ZM diy amp assembly 101! Znaš da je netko sjajan kad sve što radi izgleda lako.

Tako je! Razlog je, naravno akustika prostorije. Naime, tada se jače čuje kad nekome tko je u gostima padne vilica na pod kad krenu prvi tonovi iz zvučnjaka!

Still in mechanical realm, sort of Again post-Pa dealing gone wrong - Pa did arrange 2 pole switch, while hole on back side is for one pole, one pole in kit; Again no blame from my side ; I did enough mistakes that I know from where they are invoked, rest of life is not enough to learn how to prevent them I had a bag of proper 2 pole switches paper masking tape, calipers, files, patience

OK; thermal issues some facts: T bars came in Papa's arrangement, with approx 4mm Dia holes TO3 isolator pads are silicone thingies, I don't like those above 15W or so per device; gone for Mica + quality goop T bar is having bowed side which is going to meet heatsink; see sketch; some lapping - water-sand paper on thick glass is problem solver heatsink is bowed as all extruded heatsink of this profile are bowed; see sketch; no problem when you arrange adequate force with screws - not the case in this case; will rectify that

While at schematics, let's cover few things ( I already posted in origin thread about this amp), so let's repeat: well, I'm always amused studying Papa's schematics, from any imaginable reason .... mistakes being one of them :clown: original, drawing mistake marked, mistake fixed, simple remedy for better AntiBigBadaBoom at speaker out; there is no mistake at Papa's pcb, it is just on drawing now - last schm - in this moment already tried and proven, results are: edited delay circ is working flawlessly - no visible move of cone neither at power On nor power Off only if you are powering it Off reluctantly, slowly operating the switch , there is movement of cone, but slow and gentle - and even that one is not audible same behavior when leaving power switch ON, and doing power operation with mains cable of switcher - Nada during power On, gentle roll of cone with powering Off will post plenty of pics and some text, in separate thread maybe next evening and yes, really dunno how delay circ operated in original, didn't tried it at all; but I'm used to change Papathings just for sport - hard to make it better, easy to make it in different way

Zamoljavamo putnici da ne ripav... Avijon neje šrafen, lepen je

moja preporuka Darkvoice 336SE

Preporuka JBL Clip 4. Iznenađujuće radi za prcvoljak a ne smeta mu ni ako malo pokisne.

nisam, stolice - Ikea ću da nabavim neki bluetooth aktivni zvučnjak

A eto, cisto da ne bude hladna lemicica... Ovo bi trebalo biti jedan kanal MoFo-a...

Nagradno pitanje. Da li uredjaj koji kad se napravi da bude lep isto tako i bolje svira? 😁😛🤗

Dori staari Thorens ponovo svira ! I konacno sam ponovo kupio plocu, castio sina njegovim omiljenim bendom 21 Pilots / Scaled and Icy album na narandzastom vinilu🤪...mozda tripujem, ali oranz vinil mora da je bolji...kao i kabel😁

lottery done kad smo mi dobri jedni drugima bez ćeranja i nadkurnjavanja, đe će nam kraj

A pa da, ja pitam a pravio sam ACA sa switcherom - nego davno bilo zaboravilo se Lepo bre mnogo, šta da rečem. Ponosni vlasnik po drugi put uboo loterry

Sjajno 😍 kids.vidzz~tv~CdFIYKqK0lx~1.mp4
