Hi,
I had been using an X-10D clone which has wiped out both my tweeters and amp 😡
I'm using a different amp till I have time to look at the other one, but have replaced the tweeters and they sound ear bleedingly bright 😵
The tweeters are known good taken from another set I have and are the same Audax HD100 D25 8 ohms, reading 6.2 on my dmm (I also tried another pair, which are doing exactly the same) so I can only think something has happened to the crossovers. There is nothing visibly burnt, or charred - any suggestions as to what this could be, or to check?
Thanks.

You probably just have loud tweeters.
It's hard to be sure without knowing what your pre did, what it did to your amp and what happened to the old tweeters, but there's a chance the crossover isn't damaged.
Try using your nose to detect heat damage around the inductors. Measure anything you're able to.
Try increasing resistance to the new tweeters, perhaps use an L-pad next to them.

Please post a schematic of the crossover which would help us to determine whether damage to the crossover is even possible.
Presumably the X-10D clone oscillated and fried the amp and tweeters?
Is the new amp just brighter sounding than the one that blew up?

If it has an L pad o the tweeters I would double check the resistor values in case one opened or went out of spec.
Everyone using the totally superfluous and unreliable X-10D helping to continue the undeserved hype eventually gets what he/she deserves but I am sorry to hear you have damage. It could be that the old tweeters simply had less output after years of use.
A 47 Ohm 2W metal film resistor in parallel to each tweeter may seem a marginal difference when calculated but it may be the solution to your issue.
Wait a minute.....X-10D clone....Who wants to clone this device?

Is there a confirmation the preamp was the source of the problem? Failed coupling capacitor, or loss of one half the supply causing a sharp transient?
Apologies for my late reply. I finally managed to get back on to this at the weekend!
Okay, here goes ..
I have owned these speakers on and off (my brother had them for a while) for over 20 years and they were incredibly bass heavy and lacking in mid range, as a result I messed around with them repeatedly until they sounded good to my ears. They are a 3 way and the woofers were wired in parallel, which I changed to being in series. I know some people will cringe at this, but it worked.
I believe Jean-Paul has hit the nail on the head that the old tweeters had had it and I effectively compensated for this, by reducing the bass output. I didn't realise tweeters lost their efficiency, unless they have dried ferrofluid which these don't.
I have reverted back to the woofers being in parallel and they sound good again 😀
The other good news is my nc200 had just blown a fuse on one channel and is now working fine again!
Needless to say, the X-10d will not ever be used again!!
Thank you for all the comments.
Cheers,
Colin
