    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

JBL L-100 mk2 slike

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

Tannoy OB fun ...... brute force approach

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

Tannoy K3836 - painting da throat (completion of two previous blog entries)

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

Tannoy 3836 - cleaning da gap ......back in action ;)

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 .

Tannoy 3836 - cleaning da gap

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

Tannoy K3809 - hardened cloth surround issue - solved

I'm lazy , so there are excerpts from my correspondence on Tannoy Yahoo group; all quotes - Mighty ZM   I'm putting this here as future reference for some other desperate Tanner ; I must admit ( or I'm just boasting ) - I'm always having serius backup for all things speakers - from Aleksandar RAAL ....... even if I'm always stubborn and I'm bugging him only post hoc ..... to be sure that I didn't blew something           of course - "Danish guy " wasn'
