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
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'
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
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
bias & offset procedure done
clipping test done
installed switches for tying L & R inputs , for bi-amp duty .
they're made with common supply for both channels in case , because of possibility of use in parallel mode
in any case , when made as dual mono , wiring can be cleaner and nicer .
whatever , I'm satisfied .
bottom taster buttons will be replaced later ( pair of "START" buttons per amp just doesn't make much sense ) , and missing Cardas posts on one

Workmanship - by well known local speaker maker
Sonido SCW300 in MLTL , Sonido SWR200-8A on top , xover 6db/6db , pretty low parts - as per Method - temporary ; they'll be replaced with cheap but good ones
btw. - that's next Manu's project
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 .

( shvatio sam da su braća u Nagybecskerek-u definitivno sirotinja - nemaju za interneta , pa ja moram da im objavljujem slike )
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 .
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 ..............
