Help to identify Capasitor - Electronic Circuits Projects Diagrams Free

craigbeal · 6th December 2007, 05:27 PM

This board has come out of my Peavey 2XT speaker cab. Seems the capacitors have gone in both speakers and so need replacing but i can find these capacitors anywhere. Can anyone here understand the codes on them and tell me which ones i need to buy (uk) ??

Codes :

XG2I
Mexico
x60
x030

Regards

Craig

I think it is a resetable fuse and not a capacitor

I would agree, or an overvolts device (MOV?) of some type - not a capacitor.

I like the light bulb as a compressor. It would make music have jerky levels. Speech would have a loud attack at the beginning of each syllable then fade away until the next syllable.

It's presumably there only to protect the tweeter?, in case of too much power it drops the level to the tweeter - in normal use it will have no effect, and even in overload it won't have that much. It's a common (and cheap) protection system.

Hope the MOV did its job, but I wonder if what took it out might still be a problem when replaced.

If the level is turned up high enough to cause flickering of the light bulb then the sound from the speaker will also flicker.

Only from the tweeter, as that's all it will feed.

I fear that the MOV is improperly wired. there has to be additional protection to safeguard the board- leave alone the MOV. Had the designer shifted the MOV on to a mechanical screw type mounting the board could have been saved from burning

Now Craigbeal has to somehow salvage it, carving out the burnt portion, manually locating the new MOV elsewhere, and hand wiring it.

I would think you could remove the MOV, make sure the traces are good and see if it still works. If so, replace the MOV if you can find out its voltage.

I have this same problem with this same exact board...I'm wondering if you ever found a suitable replacement for the MOV

ELM · 18th August 2009, 05:04 PM

We have these available if you need them 01708680971...

Thanks!

I doubt it's a MOV, it's more likely to be a PTC.

Nigel is correct that the bulb is there to protect the tweeter.
