This is most likely a stupid question.
I just got a Laney Cub 8 with that socket.
What happens if instead of a cabinet, I use it for plugging headphones? Blow-up?

Good question, that would be a fun video to watch.
That socket is not for headphones, is not a line out, is meant to be use as a speaker conector. Just that. Dont use it for anything else.
How that laney sound? I know that is a Champ Clone, but I wuold like to know how it sound.

"Good question, that would be a fun video to watch."
Mmmmm...not so much. I can only imagine the nasty shock that might give the wearer of the headphones.

Doesn't Duke Berryman have a box to convert that signal to line level? Just a thought.

Rogon, that's the problem having no headphone out.
The Laney is supposed to produce a satured tone at high
volume, but I have neighbours, and 3 mics to test!
What I'm surprised at, is that no feedback occurs.
I'll try to find that box mentioned by orphan.
Anyway the sound has no comparison with those produced by solid state amps.

OK guys, I was wrong. DukeBerryman was talking about the Radial Re Amp. It can't handle the signal level of a Spkr. Ext. I did find out there is a small company that does make an active(instead of passive) attenuator. It is variable and can be fitted with an XLR-1/4" out that can then be plugged into earphones, PA,or amp. This is called the Ultimate Attenuator.

laurent2015,
Yes, a 5w tube amp is to loud for the house.
You can use an attenuator. It will give you what you want (breakup at low volume) and is not that expensive for a 5w amp.
orphan, as far as I know, the problems whit attenuators is that when you use it to much it affects tone. But, affects first to the higer frecuencies, wich is a very bad thing for guitar, and not bad at all for harp.
I guess that whit any attenuator you are going to be fine.

@ rogonzab
This is from the Ultimate Attenuator site. It is written by Victor Mason. He is the owner of Plexi Palace and Mojave Amp. He is talking about the problem of frequency loss and how the AU addresses it.
"Now what about the tone. The load is so far mismatched, how can the sound be correct? The UA has a built in low impedance power amplifier. The term low impedance means strong high frequency response and with their well crafted internal audio coupling, they have managed to retain and preserve the sound quality while keeping the amp at a low volume. The reduction of actual power is safer and the audio quality is preserved and enhanced via the audio coupling circuitry as well as the built in low impedance power amplifier, which does exactly what you need for low volume high frequency preservation."
You can find the complete thread here:
http://www.vintageamps.com/plexiboard/viewtopic.php?f=1&t=81179&start=45
I have always thought, generally, attenuators cause more problems than they solve. But after reading the attenuator history on the AU site, I think this attenuator would be very useful in keeping the tone of a cranked amp at lower volumes. It also appears to have options to connect to a variety of equipment.
Edited to add: Looks like it is a very expensive way to get a cranked amp volume into headphones!!! Probably no help to laurent2015.

I played the laney 8, 10, and 12. I thought the 8 was pretty good, but I dunno about the speakers they use. That's mainly what I remember, was wondering about the speakers. May have been a phase I was going through at the time though...
I've forgotten which one, but one of those amps stood out as superior for the harp, and one was definitely not so good. I think neither was the 8. The 8 was pretty good though.
The best laney amp I have played through was the LC15. I'd happily have one of those.
Yeah Laurent, I'm afraid the cheapest solution for you may be to change your way of living. Everytime I consider a different housing option, I remember that not everyone has the opportunity to play their stuff at some time every day.
My neighbour is a drummer, I leave him alone, he doesn't bother me. The guy who lived there before was a 90 year old war veteran. Deaf as a post.
My other neighbour is a man of bad character . I don't care what he thinks. His reputation is so bad, neither do the police.
So if you can find a location with other loud people, deaf people, criminals etc, I think things will be much easier.

Yes, makes sense to me Rzab, the 10. I think the 12 is really a quite different amp, and not so nice for a mic.

Every attenuator I've seen is more expensive than the amp!
Now: I own an electrical module I can use to plug several headphones, and each channel is provided with a volume control.
What if I plug that module in the socket designed for the cabinet?
Does such a process cut off the loudspeaker of the amp?

The module for your headphones sounds similar to the Jamhub. These are for line level or instrument level signals. The Ext. Spkr jack is a signal from the output transformer. It will fry a module that is made for line/instrument level. The Ext. Spkr signal would have to be attenuated for what you want to do with a headphone. The speaker of the amp is not cut off unless you unplug the jack from the spkr. Never run the amp without the jack plugged into a speaker or an attenuator that will let the transformer see a load. Otherwise you will burn up the transformer.

@Orphan, Rogonzab and Superbee
Guys, I didn't listen to you and tried the experience plugging a headphone in the socket designed for the cabinet.
I did it after discussion with a member of my family who said "your amp needs a 8 to 16 ohms cabinet, it will not make the difference with a 8 ohms headphone"
OK, now your eardrums make the difference, and I carefully kept the volume control under 2...it worked without problem, but you don't get THE sound, of course. Moreover, the amp's speaker has actually been cut off during the process.
Now, the most important: I plugged a distortion pedal with a lot of controls on it: my Laney comes close to sounds I like for the harp, not to compare with a solid state amp, with the same pedal.
I realize that combining the different controls (with different mics, also!) will take a long time.
I'll have to take notes!

laurent, it sounds to me like your socket is actually an EXTERNAL speaker jack rather than an EXTENSION speaker jack. Kind of confusing as they're both usually labeled with the abbreviation "EXT", but there is a difference. External jack will cut off your amps onboard speaker, and just run whatever speaker you have in the other cab, or in your case, the headphones. Extension jacks on the other hand are meant to run in parallel with your amp's onboard speaker at the same time so both speakers pump sound.

You are right, "external" speaker is written on the back of the Laney. You gave the ultimate explanation, thanks!

Thanks for the update and explanation. I stand corrected re this amp and earphones. Good info to have. Thanks again.

I'm glad nothing was damaged. If you keep the volume so you don't hurt your ears I expect it's ok. Your headphone speakers can clearly handle the power. Do you know the watts rating of the headphone?

Watts? No but impedance is 8 ohms.

Yeas, that's load, which is what your amp needs. So you just have to make sure you don't blow the speakers in your headphones, but if you have the volume low enough to not hurt yourself, it seems likely to be fine. If you're hearing speaker distortion, take it easy.
