  1. Hi all, Just managed to get myself a pair of AR11 complete with what looks like the original foam grills. The woofers have been reformed but with a slightly smaller roll foam rings. They sound wonderful. I will listen to them for a while before open them up and see if anything will need replacing. Best regards, David.
  2. Thanks Roy, The tweeters have red/orange domes so I will need to get some aluminium solder ? Best regards, David.
  3. Hi there, I also have a pair of 2ax, and problem with one if the tweeters. My problem is slightly different ! One of the leads has snapped off and I tried to solder them back but it wouldn't take the solder. Does it need some special solder ? Is it aluminium wire ? Your help would be much appreciated. Best regards, David.
  4. Hi all, after going through the steps suggested, I think I may have tracked down which bit is causing the buzzing noise. 1. Connect power amp to speakers only, no buzz 2. Connect preamp to power amp and speakers, no buzz 3. Connect a cd player to preamp, power amp and speakers, buzz..... even with the power off on the cd player. Remove the cd connection ,then no buzz. So it looks like that it is the connections before the preamp ! I do have a simple 'ground loop isolator' and I swear that it didn't reduce the buzzing noise when I tried it before. I think I must have connected it to the wrong point. I have now connected it between the source and the preamp all all very quiet, no buzzing noise. Thank you all very much again. Now I can go back and enjoy some quiet quality music. Best regards, David. Hi all again, After doing some not digging around and think I have found the real culprit of the source of the buzzing noise. Following Carnivore's direction of investigation, I have identified that the power block - Tacima CS947 - is the source of the interference. I have now replace the power block and the ground loop isolator and all are quiet . Thanks very much for all your help. I can now stay 'budget' for a little longer. Best regards, David.

  6. I know LST and budget cannot be spoken in the same sentence ! I have tried swapping out the LST with a pair of 3a and the buzz is still there. However, if I use an integrated amp then they are dead silent. The integrated amp that I have tried - Pioneer SA-508 and Yamaha DSP-Z11. The Pioneer is obviously very under powered , the Yamaha is much more powerful but it does get a bit warm. I am using the Yamaha to drive a pair of 9s. A Mcintosh will definitely fits the bill but way over my budget. As some other guru here use the Adcom but they are rather difficult to get hold of here in the UK. I am trying to see if I can make the best use with the equipment I have before spending . Best regards, David.
  7. Hi there, It's been a long time since I last visited. I have a question and need some recommendation on a preamp for my setup on the LST. I have a Crown XLS2502 which sounds good for the LST when connected with the AR-C06 preamp, but it has a constant buzzing noise on both speakers. Tried with the Xiang Sheng 728a preamp, the buzzing noise has improved but now they sound very thin on the bass. Looking for a reasonable preamp on a budget that could work well with the Crown and LST ! Any information is much appreciated. Best regards, David.
  8. I can't remember exactly where I bought them from but these are exactly the same items. https://www.aliexpress.com/store/product/New-20-pieces-19-43mm-4-ohm-19-43-mm-Without-diaphragm-Tweeters-speaker-voice-coil/508259_32812762272.html?spm=2114.12010612.8148356.49.6caf5ef17HvQ0H or these https://www.aliexpress.com/store/product/10-piece-19-43mm-1-silk-diaphragm-dome-Tweeters-voice-coil-4-ohms-100-new/508259_32271734227.html?spm=2114.12010612.8148356.3.6caf5ef1saAQif
  9. I repaired a pair of 94er sometime ago. The surrounds were indeed on top of the cones and not under. The picture below shows the before image.
  10. The overall height of my stands is just under 21". The legs are made from 2x4 timber and 1" plywood for the top and 2 x 1" plywood for the bottom. I used the leftover materials that I have but obviously you can go with much better wood timber like oak and others. I have painted mine black to match the cabinet colour so it doesn't really matter what type of wood but as long as they are strong enough. Those stands can take my weight with no problem. I have also used some sort of thin carpet tiles - the ones with a soft plastic backing - to go underneath the stand, plastic side down on wood flooring so that you can shift them with ease while trying to find the best location for them.
  11. Welcome Jimmie, Have you tried turning the midrange control back and forth and see if you get any output ? They do go rusty .
  12. Hi Sudhir, I can't really remember what model that speaker was ! I didn't have to redo the veneers. I think it is something to do with the humidity over here being reasonably constant so most of the speakers I have seen are in good conditions. I will try to find out what that speaker was. The one that AR18 is sitting on I think is the AR14.
  13. The cone was from the AR3a when I destroyed the coil trying to fix it. The coil was from a Chinese supplier. There is still lots to experiment if I want to put it back to the original tweeter body !
