sve je lako kad sebi pravis - sto pogresis, to ce i da ispravis, pa valjda neces ponoviti gresku ( vise od 2 puta) drugo je kad pravis za drugoga, onda je svaki sraf bitan za razmotriti ene moj T-Bed za primer - sve je namerno ofrlje ili bar nenajbolje al zato M3 srafsovi+matice za stezanje mosfets na hladnjak - striktno garantovano 8.8 kvaliteta ili u najgorem slucaju prohromski (oni nisu 8.8 ali sigurno nisu napravljeni od pocinkovane zice), pa stezanje sa moment surafciger kog su zmije ujedale, taj se i gustera boji ..... pa mu cizme postanu navika moral of the story - mikumov sraf - kirner u sredinu krstastog utora, udariti cekickom od 200gr, jednom ostro ce se lako desi da to da dovoljno deformacije da ukloni ugnjecenje msm, ono, svi putevi vode u Rim moz i Nixie da ga stavi na kuglagere jedno po godine, odvrnuce se i sam od dosade

nemoj silom, uzmi veći čekić

jbte ja nisam znao ni da to postoji ........ a kamoli da razmisljam o bakru na tome alsamzaosto

nesto mi se pricinjava da taj Mogami nije srebreni, dakle rokaj obican kvalitetni tinol neka korist, kazem, kad je sve srebreno, pa da se i ti usaglasis sa lemljenjem ovako ni po brige Aleksandar Kujučev WWW.RTS.RS Brzi, brži i najbrži bendovi devedesetih

a koja je zica/kabel?

zapljuni ga brate Kujo jedno je kad imas sve elemente srebreninu, pa onda ides radi kemijanja da ima srebreninu i u tinolu ene, slusao sam te neki dan na rbg2, istina ne celu emisiju a posle mi ne proradi mozak da nadjem i preslusam

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

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

o0o

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

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

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

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

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

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
