The life just disapeared

My system has lost its life.
I have absolutely no idea what has happened

Bass has gone recessed and muffled, and the highs are screaching. The soundstage has just disapeared. Some recordings sound like a tranny radio
This has happened within the last few days, i havent changed anything for over 3 weeks

 

Mains?

Blown tweeter?

Melted capacitor somewhere?

 

...and the Deadly deMagic hasn't even got to you yet...

 

Mains havent changed (fairly sure)
speakers seem OK, lack of bass more than anything else but woofers still move
havent checked caps.

forgot to mention, it seemed to happen to one channel first, but now both

 

Switch it all off. Unplug everything. Clean all points of contact. Put it all back together again.

Try using headphones to rule out speaker problems.

Try using a tuner to rule out CD player problems.

 

Ill try the cleaning, although it was all dont start of December.

Not got any headphones, or a socket. But the problem is apparent on Vinyl play aswell as CD.

 

Penance, was it not you that had to re-solder the speaker terminals on your amp a few months ago ?

 

yep :shame:

ill check that tonight

 

Penance - if the fault turns out to be as voodoo has suggested then I reckon we should all tip our deerstalkers to him....that was pretty impressive deduction.

 

Sure was
Im secretly hopeing he is wrong, otherwise i have to admit my soldering was pants!

 

It'd be very unusual to have two solder joints go off like that in a short period of time. Also, solder joints usually either work or not, having the sound "go off" like that because of solder joints in the speaker terminals would again be unusual.

Check your system set-up carefully. Anything unusual?

What do you have in your system? Did you play some very loud muic before the sound went wrong?

 

Nothing unusual, havent changed anything for a while now.
was listening a tad louder than normal a few nights back, but only around 10 o'clock position.

 

Andy, personaly, I would check all connections, & joints, power leads, then start looking at caps, does sound to me like maybe a cap prob. Tone

Will i be able to spot a bad cap?
I dont have capacitance test on my meter:/

 

It's a tricky one mate, do check the basis first before diving in, supply rail voltage devations if any etc, sounds like a psu side cap, a cap meter is useful, but you should have 2 channels, so compare one against the other (It's cude but will give you an idea) if anythings wrong there.
Usually is simple Andy, check also board connections and ground planes and the 0V rails. t.

Just found a cap test meter at work i can borrow

 

stuck a disc on when i got home

sounds as usual now

 

Look for little green creatures hiding under the transformer.
Them bloody gremlins get everywhere!

 

i rekon they might be in me head; /

 

pennance,
it probably was the electricity, they've probably been trying out broadband over the national grid in your area or something.
either that or you're insane, obviously.....
nice avatar btw
cheers
