    Hello, I have a bugera infinium 333xl 212, I bought it at the end of February, and since June I have the following problem, it tells me that valve # 3 fails. I contacted the seller, they did technical service, they replaced valve No. 3 They replaced all of them, but the problem continues. The moment they returned it to me, I tried it and it worked well for 3 or 4 hours, I turned it off, the next day I tried it and led # 3 came on again ... At one point, led # 4 came on, inclusive, and even standby blinked, the amp completely shut down and didn't turn back on, they fixed it, it worked again, and the same problem again after a few hours. I'm starting to get disappointed because I can't enjoy the amp. Did the same thing happen to someone?

      Nigel67 Hi. I am sorry that you are still experiencing an issue with your unit. It may be an issue with the device that holds the valve. Where are you based? I would suggest that you go to the support tab at the top of the page and submit a Service ticket. We can then get your unit to one of our service centres and give it a thorough test. Make sure you write on the case that a repair has been performed, but failed virtually straight away. Can I also confirm that you purchased the unit brand new in february? many thanks

      EmanVeg27 Hi Nigel, thanks for responding. That's right, buy exactly on 02/28 of this year. In June this problem started. It was heard like a tap and then led n came on. 3. I have already created the ticket: CAS-130446-N2Y4X1. The owner who sold the house serviced it 3 times and the problem continues.

      Nigel67 I just looked at the case. It is with our Vegas office. This unit, if the serial number is correct was manufactured in 2011, so very much out of warranty. I do not know who the nearest service centre is in Argentina but whoever handles your case will be able to advise you further. With your unit being this old, it could well be the device that holds the valves or possibly other components starting to fail because of age.

      EmanVeg27 Thanks again for answering, most likely if it is an old unit, unfortunately this is my first experience with these equipment, hopefully there is a solution, the company that distributes in Argentina is TEVELAM, today the retailer contacted them and coordinated the shipment to their location .

      JMaxfield77583 Bias Circuit is failing. I have a TriRec that did the same thing. If you know how to use a bias meter, and a multimeter you can figure out what's causing the problem pretty quickly. The schematics are online with test points. If your issue is like mine, it could be the rectifier circuit or the autobias circuit. The Infinium amps are cathode biased - aka self biasing - but do not always work right because they may be set from the factory out of tolerance. You'll want to figure out the correct plate voltage, then set it for 60%-65% bias current based on the expected power output of the tube your using. There again... with a cathode biased (self adjusting) amp this may require some fine tuning of the components themselves. For example, if the factory installed a 47 ohm bias resistor but it has a +/-10% variance in actual value, you could be off as much as 10% of the target... which would result in burning up tubes and other board mounted components. You might have to do some shopping around to find better quality components and then have them soldered on. The circuit designs are sound, but the component quality used in these amps is total garbage... that's why they have so many warranty claims.

      WORD OF CAUTION: If you are not experienced working on electronics, or high voltage... DO NOT try this yourself. You could kill yourself.

        EmanVeg27 Hi John, thank you very much for answering. Two months ago I sent the team to the headquarters in Argentina, TEVELAM. Apparently they found the fault in the valve plug and a part of the plate, they were going to test it for a few days to see if it didn't fail again, then they would send it back. Hopefully it was fixed ... Thanks again for replying. Greetings

    Hi, I´m from Brazil and I´m Electronic Engineer. I have a costumer with a Bugera 333XL Infinium which does not fit the BIAS to valve 2. I just change the tubes to new ones, two new quad sets (JJ and electroharmonix) but the led 2 of digital module turns on and the standby bulb light blinks. I have checked the grid voltages and to V1,V3 and V4 the voltage is -48V. To V2 the voltage is -25V but not stable, it changes between -25V and -24V. I have checked all cables, I removed the digital module and checked connections. I have changed the sockets of tubes but the problem persists. I have no ideia what do know, I suspect that infinium module is bad working. thank you for help.

    The ticket is: CAS-129532-V7J5J8

    The portal won't let me send the request. It keeps saying to fill in the required fields and they are all filled in. I'd just like to call or email somoene at Bugera. Why can't I do that?

    Any idea why the lights don't work on the pedal? I bought the head off Sweetwater as a return and it had no pedal. I ordered the proper Bugera pedal. It switches the channels and turns the reverb on and off just fine, but the lights don't work on the pedal. I bought this head a couple years ago and Just started playing it, so I doubt anyone will do anything at Sweetwater or Bugera. But if it's a fuse or something, I can fix that. 

    Any help is appreciated.

      Dale_M At this stage it is difficult to advise if it is the amp or the pedal, your best bet would be to see if anyone else you know has either models and you could try either the head or the pedal to at least conclude which is at fault.

    Still waiting to hear from a request for the availability of a 120 v transformer for a used T-50 that I purchased.  How long is typical to wait for a response after submitting a request?  Anyone have a suggestion for me?

    Hello I recently purchased a Bugera V5 amp which sounds great but I didn't realize until later that you also offer the T5 which is just the head and not the combo like the V5.  My question is are the V5 and the T5 tonally the same amp?  Is the T5 essentially voiced the same as the V5 with more eq options just minus the speaker?  Are they voiced differently?

    Also the speaker output says 4ohm minimum so I am assuming that 2 12" speakers wired in parallel will be fine for either the V5 or T5?

    thank you

      WilliamR Hello, The v5 and the T5 are similar but they are not voiced exactly the same. The V5 preamp design is more of a '60s vibe design, the T5 is more British voiced. Two 8 ohm speaker wired in parallel would work fine for the T5.

    I just received a secondhand V22 Infinium. It sounds great, but the FedEx guys taped bubblewrap directly to the amp and it left some adhesive residue.  Is it safe to use Goo Gone on the Tolex? Is there a better option?

      Nigel67 Whatever you use, I would suggest that you try the cleaner on an area that is hidden or least visible. No matter what you use, it could react with the material. I found a video of a guy who cleans up his tolex but the substance he uses may not be strong enough to remove the tape. https://www.google.com/search?q=tolex&rlz=1C1GCEA_enGB815GB815&oq=tolex&aqs=chrome..69i57j0l7.1662j1j7&sourceid=chrome&ie=UTF-8#kpvalbx=_J18qX_3bL-qp1fAP4OyamAQ3
      Isopropyl alcohol may also be worth looking at to clean the Tolex but again try a spot out of sight first of all.

      PatrickCorrigan I would try a citrus-based cleaner like Goo Gone. It works well for removing tape adhesive, but the citrus smell will linger for a while.

    Hello,

      I have a Bugera G5 (that I love) and I also have a Boss MS-3. I followed the instruction in how to make the MS-3 switch channels on an amp. The MS-3 switches another amp I have, but on the G5... uh that's a different story. It seems it switches the channels at times, and sometimes it doesn't. I bought the amp used, so I don't have the manual. I tried pushing the channel button and that doesn't seem to work. Can anyone help me out with this, please?

      WilliamR Hello Joe, If you are using the Boss MS3, be sure you are using a TRS cable on the CTL out.

        JoeRojas Yes, I am using a TRS cable. That's how the amp switching works on my other amp. And I did plug the TRS cable into the CTRL 1/2 Out. And from the CTRL 1/2 Out to the Footswitch in of the amp.

        WilliamR Hello Joe, It appears the Boss MS3 may not support dual button footswitch function. So using a mono 1/4 inch cable should give you the ability to switch from clean to overdrive but not turn the reverb on and off.

    Good day! So I own a Bugera G5 amp head and absolutely love it. A couple days ago it started losing power or something to that nature. My emulated output does work as well as the send/return. I've changed both tubes now... Not sure what to do at this point... The distortion, loss of power only happens at the amplifier output to the speaker. I've checked my speaker, cables and tired other guitars.  The infinium LED for the tubes sometimes lights up even at a low wattage and even though I've put in new tubes. I give up and need help. Please help!

    I'm looking to purchase 2 new cabinets for this amp. I always biamp so 1 cabinet to channel A and 1 cabinet to channel B through the crossover.  My question is what should be my Ohm rating per cabinet? 2 x 8 ohm cabinets or 2 x 4 ohm cabinets? And what should be the minimum wattage of each cabinet?

    Please help, as I only want to buy once and cry once!

    Joe

      DaveMorrison Minimum impedance is 2Ω/channel. You could run a cabinet with two 4Ω drivers in each cab. You can safely run a cab with two 8Ω drivers; it just won't be as loud. If you run at full volume at 2Ω, you theoretically need a cab rated a 2000W.

      JL1103 Just for clarity, when Bugera states 2x1950w/2 ohms, In the owners manual, you divide the wattage by the number of cabinets? If this is correct, 2x1380/4 ohms would mean 2 x 8 ohm cabinets at 700 watts each should cover the amps out put?
      • July 21, 2020
    • JL1103
      DaveMorrison The manual is not so clear, probably because it's a muddy subject. Perception of power is tricky. If you have a 100W amp and want it twice as loud, you need 400W. Amps are also measured using sine waves from test instruments. Since the power output of your amp is dependent not only on the amp's gain, but also your input signal. The way you play affects the power you produce. Rating cabinets is difficult because of the unknown factors: how was the amp measured, and the "quality" of the input signal. A distorted signal (Fuzz and overdrive) has more "energy" than a clean signal.
      If you are a clean player and don't play a full volume, then 700W ought to be fine. You could probably use a vintage Fender Bassman. If you push it to the max, you could "toast" nearly anything.
