Hi all, I'm having a real hard time with my burgera 333 head. The issue is with switching in between chanells on the head or foot switch. It will only stay on clean and won't switch to crunch/lead. It also intermittently switches the boost on and off from time to time. I had taken it to a tech who thought it was the relays and he changed these out. He then said it was tbe pcb board (PCB 722000REV) and would need replacing. He said it would be a simple install, however getting that part He said "seems impossible". Can anyone help me here? Many thanks

Hello, I just purchased a G5 infinium. It was working fine when all of a sudden it didn't. Now I have almost no volume, I have to really bang the strings of my guitar with the volume up all the way to get any sound. The sound that comes through is very fuzzy and pops a lot. I already tried new tubes and the problem persists. It's my first tube amp and it's made a bad first impression of bugera. 

Hello,

Can I run my T5 Infinium without a speaker cabinet attached, using the headphone jack into a mixer, or do I need to attach either a cabinet or a load box to the speaker output first?  I have no problem either way, but I'd like to use this thing at practice, but I'd rather not lug along a speaker cab with it as well...defeats the whole purpose for me.

Thanks in advance.

Hello people,

My V55 is making these horrendous popping, thunderous sounds when some volume is applied. Also I can not get any reverb out of it, as well as noticed the Bass, Mid and Treble have very little or no effect. Replaced the Tubes, re-seated the tubes several times, checked for cold solder joints, I have tested both the +15 and +5 Vdc out of the 7815 and 7805 Regulators OK. The amp plays my guitar OK, nice and clean, when it is not going crazy with the horrible popping sounds. I am thinking that maybe my main board has gone bad?  Or could it be the smaller daughter card that runs the reverb, that has gone bad. Any ideas?  I also tested that the problem is there in both Triode and pentode mode. I am going to try to remove, one by one the pre-amp tube, stages to see if the problem appears to be stop. Maybe get lucky and a resistor or cap in that area has gone bad. But at this point I am really stuck. I have opened a ticket with support, but they must be very busy. (have not heard back from anyone yet) My support case # is CAS-488499-W9D1K4. I also am trying to find out the cost of both the main board, an also the smaller daughter card that is attached if it is not included.

Good morning everyone I have a Bugera 333 just wondering how do I order parts on this site?

Don't know what the board is called but it's for you plug the main power cord in it is a small circuit board with the fuse and the off and on switch. I hope the image helps me identify this board and where I can get one thanks in advance everyone

Hi everyone.

I have a bugera 333xl and i want to ask if i can control the channels with my pedalboard (boss gt100) . I play with 4th cable method but I don't use the preamp from pedalboard So I need to control lead clean  channels of bugera without use the footswitch . Can i use midi cable to connect pedal board with the amp footswitch? Or buying a midi controller ? 

Thank you .

Hello,

I've recently bought a used Bugera amplifier. After I plugged it in, it turned out that the LED at the front keeps flashing with more or less one second intervals. At the back, there is also a LED which signals the need to change tubes. I replaced both tubes for the ELECTRO-HARMONIX EL84 model. But after all that, nothing changed.

What can I do to fix this? I have an electronics degree so I can measure or replace any electronic elements. Unfortunately, I don't specialise in tube amplifiers which is why I'm asking for your help.

Thanks
