Be's Millenium 6000 repair/WBT termination

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

Taming da Beast - Stratocaster

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

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 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 .....

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

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

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 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 .....

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'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   if you're puzzled - here is a link for SigJenny sig gene proggie : http://www.natch.co.uk/downloads/SigJenny/SigJenny.html
