I can go buy it tomorrow. I have to decide in a few hours. The problem is.... I can only play it through headphones. The seller says the headphones work just through the speaker output jack using an adapter. I guess the power amp is OK if there is a sound at all, but what if it will just die when I plug it into a cab? I wonder how the Infinium tech handles no speaker load

BTW the amp is a Bugera Trirec Infinium.

ArturPr Read the manual for that amp and see what it says.  Plugging headphones into a speaker cab output is typically BAD and lets the magic smoke out that makes the amp work. . . 

That "adaptor" would have to be some sort of load device that has a headphone out feature, which are not cheap.  

Read the manual!!!

yeah I'm pretty much going to vote no.  Sounds like a scam.  Bet he wont let you try it before you buy it either.
You cannot plug your headphones into the speaker output.  Period.  Unless this

But my guess is this is not the case, and you're in a panic over buying a busted amp

well if the headphones work, then the poweramp works too..... I will check the manual. I can try the amp at the seller's place so if something is wrong I simply won't buy it

No.  You need circuitry after the power amp in order to use headphones.  

You need to take a cab to test the amp with.   What are you going to use when you get it home?  Not headphones plugged into the speaker cab jack. . . at least not for long.

I meant that if the poweramp is dead, then even headphones wouldn't produce any sound (because no signal, duh)

I will use it with a 4x12 cab but I can't take it there, I am on a trip and I just so happen to be near that seller
#7
ArturPr I'm always one for a deal but this is sounding like a pass if they are using headphones through the cab jack AT ALL.

Try to learn what that "adapter" is and if they are talking about a 1/4" to 1/8" adapter run.

If the amp hasn't died yet and you do buy it, replace the power tubes ASAP.

ArturPr it's a Bugera. You have to negotiate down to $100 or less to cover all that.

Please copy and paste this a million times because I'm too lazy to do it for you.

#12
I don't need a power soak or a headphone adapter. Also, 100$? Maybe there in America you got them cheaper... A new one here is like 750-800. This one is on sale for like 460$ (approximated, dunno the exact usd conversion)

Also, will the world ever stop bashing bugera for their early non-infinium products? I had a few very good experiences with newer bugeras
#13
No headphones to a speaker out ever. It will could fry both the amp and the definitely will toast the headphones. Really bad idea.
Yes I am guitarded also, nice to meet you.
#14
ArturPr you could say it's a Dumble or Deizel or Engl and we'd tell you the same thing about headphones in a speaker out jack - the amp is fucked.

I came up with the $100 like this - they go for about $400ish here. A new set of power tubes is $100 - $120. Assume $75/hour for bench time. Add some parts and $100 may still be too high.

Everyone on this forum that bought a trirec had problems with theirs soooooo

I don't plan on using it with headphones. Learn to read.
Also, the trirec has a varipower attenuator, which lowers the power to 1 watt. I learnt that the headphones used are 32ohms per channel which means they can place a 16 ohm load on the amp, which I guess is enough to prevent the amp from killing itself

at this point I think my best course of action is to never help you again. if you put a 32ohm load across at tube amp output stage you will destroy it.

I can only play it through headphones AT THE SELLER'S PLACE, right before buying. Read a few posts below where I said I will use it with a 412.
Also two channels of 32ohms = 16ohms.... What's wrong with you?

I'm not an EE by any stretch of the imagination, but I'm damn good with the English language. You're missing the point being made.

People who know their stuff are telling you "never" do this. They are not qualifying that word with, "except for a few seconds" or "unless you do it at someone else's place." They are telling you that you are running the risk of seriously damaging the amplifier if you do this even once. Who knows, the seller may have already done so, which may be the reason why he's demoing it to you with headphones instead of a proper cab.

I understand that, it's just some people didn't take their time to read that I've said I have a 412 @ home to use it with. Anyways..... A Lucky (or unlucky) accident happened. I can't buy the amp anymore because I can't even get there.
So I guess thanks for help, hope better luck next time
#22
Well just for future reference, dude. Don't plug headphones into an amp's speaker output. That's not what it's for. 

That Bugera doesn't even have a headphone jack. Please do some reading on the power levels from an amplifier. 

It's a good thing the sale fell through. For all you know, the amp advertisement was placed by some gang that wants to cut out your liver and sell it on the black market.

I'm glad fate intervened, because:

I understand that, it's just some people didn't take their time to read that I've said I have a 412 @ home to use it with.


This tells me you still don't get why your post was greeted by The Great Wall of Hellznaw.

1) Trying to use the speaker out as a headphone jack- even briefly- you risk serious damage to the amp.
2) The fact that the seller said that's the only way you could demo this amp means he probably has done this before, possibly damaging the amp.
3) If you demo the amp the waynthe seller wants you to, you risk damaging the amp (see 1, above). Depending on where the seller is, this could make you liable for repair or replacement under the law.
4) If you don't demo the amp, you run the risk of buying an already damaged amp (see 2, above).

IOW, the odds of a positive result for you in this deal were close to zero. Everyone immediately recognized the seller's condition reeked to high heaven, and told you so. But you kept considering the deal.

Going forward, if you see another deal for an amp with a similar condition, run away from it. Banish it from your mind.

You hear that OP!  So if you hear the phone ring and a voice says:
"Come around next week to try my broken amp that only works with headphones into the speaker output."

With voices in the background hooting and yelling:
"Yee haw, fresh meat, fresh meat, fresh meat!"

Run far, far away, all the while remembering not to treat people who're trying to help badly and with arrogance.

I will just order a custom Polish handmade amp for exactly the same price and call it a day... No kidneys stolen this way.

I wouldn't buy an amp for someone who recommends such a thing.

Who knows what condition the amp is actually in if they think plugging headphones into an amp's speaker out is remotely a good idea.

I changed my mind about the amp, but I'm not changing my thinking about *your* lack of knowledge. The amp doesn't care if it's a speaker or a headphone, if it's 16ohms then it's right. It can't handle the power? If an amp is 100 watts it doesn't mean it always pushes out all 100 watts. Still, I would NOT do that. Ever.

Anyways, you are right on that the seller has no knowledge and I should not trust him. Indeed I don't.

100 watts is only the amp's RMS wattage based on averages of what the amp can reproduce. The amp's peak wattage is several times greater than that. Even if you only have the amp at a fraction of the maximum wattage, the amp's peak wattage can still be enough to blow whatever headphones you have plugged into the speaker out.

This is the real reason why using a speaker that's lower power than the amp is a bad idea. Because even if you turn the volume down, the amp's peak power can still kill the speaker.

Several times more? That would mean my friend's rig should be dead as he uses a 100 watt jcm800 with a 50w cab. Even for rehearsals and live. Guess what, after more than ten years he has it, nothing happened.

If you're not actually USING all of the power the amp can produce, then your 50w cabinet can be just fine.
The other news is that some speakers are rated conservatively and can handle more than their rated amount for short periods.
The other news is that you really do NOT want to run headphones directly from the speaker output of a 100W amp.
Ask the guy who is building your Polish hand-wired about that.

For reference, the power rating on your headphone speakers will be around 1 milliWatt(0.001 Watts, if you prefer). So the power output on a Bugera Trirec that works would be ONE HUNDRED THOUSAND TIMES GREATER than the headphones are rated for.So even if the were a matched impedence, something is going to melt and/or explode if you try to run that thing straight from the amp out into headphones.

You got a bit wrong with the power rating but you are right. I don't doubt that when the headphones fail, the amp will self-destruct. The thing I am taking about is that the amp will be fine *as long as the load is there*, and headphones theoretically can be a load under those very low powers.

Anyways.... Do we still have to argue? I chose a different amp, the thread is over.

Which may happen faster than you can switch the amp off.

...the amp will be fine *as long as the load is there*...


This is akin to saying "My car will be fine as long as that tractor-trailer stays on the other side of this piece of wet toilet paper."

1) Yes, because to most here, you're still not getting it.
2) Yes, because people other than the participants will be reading this thread. Even if you never get it, others may be dissuaded.
3) Yes, because this is the Internet, and arguments (and porn) is what the Internet is for.
