I just need to know where to find TANNOY ?? My Reveal 6D needs repairing (...one has failed)

Derrick, not all cabinet speakers were meant to be replace, not saying it can not be done, but they could be epoxied in.

Have you checked the earth on the FOCUS?

Hmm, what killed the tweeters? Over-exuberant operation? What's going on with your amp? Is it being pushed into stress or distortion? THAT will kill a speaker faster than clean high power.

u could only find it inside the amplifier!

Hi,low hum from monitor speakers are usually when there is not shield connected to the cables your using for connections. Also it might be from the power light,if there is no earth or ground connected before connecting the power source in that room.

So you will need to check the cabling properly and check how the (sleeve, tip and ring) are connected and also check the power outlet,if the (red,black and yellow or white) are connected properly.

after checking those if they are OK,that means the fault will be from the speaker itself.\

Just do a proper troubleshooting.

Thanks for using fixya.....

What you need to do is connect a 1.5 volt battery to the speaker(s) terminals for a split second. Put your ear to the tweeter at the same time (you might someone to help you do this). If the tweeter "pops" it works, if not you might have blown them. The best way would (to be certain) is to remove the tweeter from the crossover inside the unit.
Tweeters are the first thing to go when the speaker has been connected to an amp that is wrong for them or they have been run at high volume.

Hiya, i assume for now that you mean the 16dip switch. If i remember correctly it is solder directly to board (could be wrong). If you are comfortable with doing this, it will need to be opened and resoldered probably for dry joints. If not then suggest hunting out a friend with some solder experience. A word of caution though, shorting out solder tracks etc could result in damage so only do it if you are comfortable. If the dry joints are really bad (sound like they are) you should be able to see them clearly and resolder (look for not so bright and shiny solder that looks cracked. Magnifier helps)

Hope that helps

One possibility is that the mute switches on your speakers have oxydized contacts INSIDE the switch - this kind of malfunction mostly occurs when the equipment is exposed to moisture and/or smog.

The most common solution is to change both switches, but they can also be disassembled and cleaned up (which is a bit more complicated and time consuming).

Another possibility is a dried up filter capacitor in the power supply or somewhere in the preamplifier section, possibly also a bad preamplifier chip but if your speakers work fine (with the exception of the mute switch noise), then the problem is more likely with the switches.

Also, check the internal connectors for any dirt, broken wires or desoldered pins.

Could also be something else, you should know i'm only assuming on the possibilities and i'm listing the most common problems i've encountered so far.

I still suggest calling Tannoy, They are usually very reasonable and will give you a fair price to service a very good product

tannoy dc speakers are built to very high tolerances. they are very easy to damage if taken apart so i suggest you contact a specialist tannoy service shop.
i know a shop in london who sells a lot of
vintage tannoy speakers and he says very few repair shops are capable of fixing these dc drivers. good luck
