    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

    Fender Stratocaster tweaks , for hum reducing
    - 0,3mm Cu foil , cut to strips and fields , glued with neoprene glue to back of mask , entire body cavity
    - all Cu planes strategically connected with soldering and grounded to CT Ground - back of volume pot
    - entire wiring changed to screened two wire cable , where screen is connected as shield strictly - on upstream signal side
    - pot shafts lightly oiled
    Woland's Kidoe will enjoy , I'm sure ..............
    - ignore predominant red color on pics - it's from red velvet and my red plastic terrace roof

    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 width I can squeeze in living room , where spks must be situated
    addendum - there is bass , at least in my smallish living room ; sound is remarkable , even with crude and quick xover , without any efforts put in measurements and polishing of same ; OB is far from optimal in almost every area , but it is so fun .....

    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 bass and compression drivers - 27 & 28 Hz , 1065 & 1075 Hz

    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 ...... but without 150E spent unnecessary , for new cone

    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 decide is it necessary to buy new cone (150E franco BG) , or something else can be done .
    So - all was needed is to soak spider circumference with acetone , pill it up , then unscrew 4 imbus bolts - to remove magnet assembly from basket ;
    Bingo !
    Culprit was in several steel pieces in gap , resulting in slight scratching of VC in gap ; luckily - there is no damage done to VC itself .
    So - SuperFi is one lucky guy - price for that pair , shipping included , was pretty decent .
    Beer for Ninja will be pleasure , not expense
    Gap cleaning - easiest with sticky paper tape ; put it inside , circle , pull up ; use new piece of tape for each pass .
    Then blowing it with compressed air , and again sticky tape .........
    Enjoy in pictures ....... decent and knowledgeable engineering .......
    ........ and yes - there are Cu shorting ring tricks in both bass and comp. drivers ; and - yes , there is ferrofluid in comp. driver gap ...
    One of these days I'll make re-assembly .....

    those were days .......
    Hans Dietze's ( Harry F. Olson's colleague) speech , taken from http://oswaldsmillaudio.com/underground/2006.html

    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't prepared to share his recipe ; I don't blame him
    that's why I'm sharing mine
     
     
     
     
     
     
     
     
     
     
     
     
     
    then one guy is saying that Mouse Glue is forbidden in some EU countries ; my reply :
     
     
     
    then guy asked where to search for surround impregnation goop ;
     
    my reply :
     
     
     
    then guy asked for difference sound-wise , pre and post procedure ; my reply :
     
     
     
     
    I hope you enjoyed little story
     
    In case that I remember to get cam to my workshop tomorrow , I'll make few pics and put it here , along with few pics of same drivers prior to fun procedure
     
    edit : did I told ya that each cone got 2 layers of Dammar ?
     
    all pics are after treatment , except last 3 ones - sent to me from seller , so prior to procedure ...... months ago
