    I own a Bugera T5 Infinium amp and I use my amp several times a week. Yesterday I powered up and after about 30 seconds the jewel light began flashing and the the tube monitor light on the back lit. I have two power and two preamp tubes so I swapped out preamp tube 1 with preamp tube 2, no change. I then swapped out power tube 1 with power tube 2, no change. I then swapped out preamp tube 2 with preamp tube 1, still no change. This seems to confirm the issue is not the tubes. If I set the output to 5 watt, turn volume and gain to 10 and engage the phat button I can hear the amp is sending a signal to the speaker cabinet, and it sounds fairly normal, just at a vey much reduced output level. This is true for both speaker cabinet and headphones out. Any advise, tricks, reset options, ... is greatly appreciated!

    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

      Dale Minaker Hi lucastor4, sorry to hear of this issue, I will ask the USA team to look out for your ticket, it looks very much like a repair will be required.

    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 Minaker 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.

    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!

    Hello! So I have had a Bugera G5 for a few months now, it's been a great amp. But a about a month ago it started crackling and losing power out of the amplified output going to a Park 4x12 8ohm, but the Emulated output does work. Changed the ECC83 power tube but no change in the amplified output. Not sure what's going on, or if It has to do with the 12BH7A but it seems to be healthy. The crackling and loss of power only happens the amplifier output. Any Ideas?

    Hi there I have a bugera 333 head and the effects loop won’t work. I connected a electro harmonic tone tattoo pedal through it and I get no sound any idea on how to fix?

      William Reichling Hello Jay Eli, I'm assuming that if you are hooking the tattoo pedal to the effects loop that you are trying to bypass the preamp section of your 333 head altogether. If this is the case, you want to go from the out of the tattoo pedal, into the effects return of your 333 head. Also, be sure to set the input level of the return with the level knob on the back of the amp. In this scenario, you will be bypassing all of the tone controls on the front end of the amp and getting all of your tone from the tattoo pedal. Since this is a distortion pedal, you would usually plug it into the amp's front end. You don't want to plug it into the send and return of the effects loop; It would not sound terrific.

    BXD15 BXD15A I would like to know the difference between those two models and how it is possible that they give 1000w of power if the speaker is 250w.
