Check w/ Studio supply (they have London office)

The cone keeps the dust out of the voice coil, I do not see a problem with you going ahead and replacing with the newer version, the sound will keep it's original composition that you can expect from Tannoy.

Speakers don't cause a loud buzz but amplifiers do. Is it possible that the input to the amp lost it's ground? Regardless, this is not why the speaker does nothing but you would want to correct any amplifier problem before hooking up another speaker. If as you say, absolutely nothing happens it is possible that you blew out the voice coil of one of the drivers but blowing out both the woofer and tweeter simultaneously would be unusual, not to mention that Tannoys can take quite a bit of guff. So the next possibility is that there is a problem internally with the crossover or,and I doubt that it exists, and internal fuse associated with it. Since there is an LED (and I don't know what purpose it serves) there has to be some sort of power supply (fused?) to activate it. It could be derived from the audio output of the amp but it would then pulse on and off rather than just be constantly on. Getting inside the unit with an ohmmeter would quickly determine what's going on but I don't know how this can be meaningfully diagnosed at arms length and therefore just can give you some generic ideas.

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

Don't know but I've a pair of Proto-J's for 5+ yrs as my main spkrs and they are the best I've ever had / heard (for anywhere near the $200/pr. price I paid) - you won't be sorry - I'm sure the pluses are great - But I know the Proto-J's are killer....the dave

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

same problem on right speaker tannoy 8d!!!

Have you checked the power supply. Maybe it has died.
