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 .....
