Help with my Tannoys

[farflungstar]

Two broken solder joints. This has been very badly repaired before. Getting in to solder is going to be difficult. Don't know if you can see.... The plate is bent backwards and I can't bend it back into place as it's fixed to the circuit board. So wires are short.

Lengthen the wires by adding pieces to extend them. Sleeve any joints.

It would be interesting to know if that was due to a user repair/bodge, or whether it's indicative of Tannoy's original work (I hope not).

I dont know but it's a bitch to resolder. Not happy!

At least you have found the problem

As Geoff says, I'd either (systematically so as not to get muddled up)replace those wires or at least extend them, I'd also use a decent power soldering iron too. But that's a result and you can now fix 'em.

I doubt that the silver in Teflon wire is standard (the clear sheathed stuff - looks very like that which Hi-Fi collective sell).

To me it looks like someone has tried to upgrade the wiring but used an underpowered soldering iron.

Hmm... I’ve just read the original post and I can see why you were asked to run a series of test tones through them. I’m afraid I do suspect drive unit damage. To be specific I suspect the voicecoil and it’s former have become partially disconnected from the cone (the mid/bass, not the tweeter). This manifests as exactly the problem you describe.

No the driver is fine. I should have tried switching outputs to see if it was replicated on the other channel before jumping to conclusions. It switched channels, buzzing replicated. So driver is fine.

I'm bloody angry with the tw*t that tried rewiring them. I can't imagine what they might have done to the bass crossovers but I'm hoping they did nothing as they are pretty inaccessible.

The quality of the job is shocking. Yes I have the problem solved - all options work as they should but it really needs someone who knows what they're doing to sort them out.

I will ask (if I can get through to them) how much a new pair of crossovers would be - though the idiot has heard wired some and not other cables of the drive units.

I can't do it - my soldering iron, and my skills, are not up to the job.

Have spoken wth Paul at RFC - he will sort them out for me so will be shipping then out to him as soon as this Christmas lark is over with.
