Prosvetari doneli odluku da štrajkuju. Ok, to je njihovo zakonsko pravo. Deca, njihovi učenici, će im se pridružiti, hteli-ne-hteli u tome, časovi će od ponedeljka na dalje, trajati trideset minuta što je ravno za trećinu manje od uobičajenih 45 minuta koji im i inače često nisu dovoljni da iz svakog predmeta savladaju sve pred njih postavljeno gradivo (skidam kapu svim onim nastavnicima i nastavnicama koji mimo predviđenog fonda časova drže dodatnu i dopunsku nastavu da pomognu učenicima da oba
few day's work ; reason for operation was - broken ends , due to too much manipulation ( they aren't exactly made flexible .... while still fragile )
intention was to dismantle them , without ruining end stickers .......... ya can call me enthusiast
however , thin foils are better ........ to my ears
btw - main stickers ( at fork ends ) are having arrows , as that cables are "directioned"
I couldn't see any fact for that , in their construction
Družili se malo Peđa, Šoba i ja
Malo testirali Peđicinu novu mernu opremicu
I napravili neka preliminarna merenja JBL 100 mk2 :
Svaka linija 2dB. Moraće da se atenuira visokotonac malo. 2dB je u okviru +/-3% fabričke specifikacije. Dakle manja promena vrednosti otpornika će biti dovoljna da se dovede u red visokotonac.
Za bas nema druge nego promena zavojnice pa novo slušanje. Kondiši za visoki i srednji u pripremi.
Malo sličica kako sam i obećao
Bas / Bass
Srednji / mid
Visokotonac / tweeter
Mrzi me da slikam
I dokaz zašto je dobro ipak otvoriti kutiju ma koliko dobro očuvana bila:
skretnica / xover
Vidi se da postoje 3 elektrolitska kondenzatora pa ću to promeniti. Veći problem je što se na slici vidi otpornik koji je okrznut. Nisam unutar kutije uspeo da pronađem komadić što će reći da je zalemljen takav kakav jeste. Tek malo dokaza da se i u EU fušeriše kad se ne vidi
Uputstvo za up
Fender Stratocaster tweaks , for hum reducing

K3809 as main driver , K3833(K3836) as bass helper
K3809 are mine , while K3833(K3836) (stars of previous blog entries ) are prepared for SuperFi's Westminster project
just having fun with some old OB "wood" , gift from Chakija ( he's not feeling young enough to continue playing with them ....... )
to be continued ...... these days I hope to have some time to mount crude xover , and put them in living room
disclaimer - I'm really not expecting real bass ....... that's max wi
remove compression driver , sand horn throat, degrease it , cover cone with paper inlets , spray-paint da throat, wait , Dammar everything ( as Gusztav made the button ) , put compression driver back
that's it - now K3833 is same as K3836 , excluding two funny golden rings ( to be precise - K3833 having gray basket and two golden rings , while K3836 having black basket and no silly golden rings )...... which will be invisible in WM , anyway .
...... A day later - measured Fs for both b
I'm lazy to comment each picture ; cleaned , horn throat sanded , degreased , painted ;
spider area on basket cleaned from glue residue
prior to re-gluing it , VC is alligned with shims made of redundant photo ( didn't had usually used plastic foils near by)
spare mesh dust cap placed just for fun ...... it will not be used
I intend to redo other driver's horn throat in black , to make them same-looking
so - pretty much same work as....or even less than complete recone .
Pair of non-matched Tanns - one 3833 (mint) and one 3836 ( supposedly needing recone ) , tnx to enormous and kind help of Ninja - obtained from outer space for my kiddoe - SuperFi .
As confirmed on net , difference between 3833 and 3836 is just here and there in color of some details ( golden ring around surround on one of them , while on other one, that ring is black) .
After some examination , measurements of all coils Rdc , I decided to make most direct and most benign steps , to de
those were days .......
