    infinium questions

    Hi, bought a 1960. I am very impressed with it for power, sound and just overall value. I have owned many excellent tube amps, both modern and vintage. I can say with no doubt that the Bugera 1960 sounds every bit as good as any old Marshalls. Yes, really.

    The Infinium system is extraordinary. Will save me lots of hassle, too lengthy to say why here, they are the same reasons Bugera mentioned.

    I am using the 1960 with 2 power tubes pulled out, to halve the power (with the impedance reset, etc). The Infinium sometimes indicate the 2 missing tubes (the two inner ones) are dead (which is correct: they are missing, so the Infinium is saying: hey, the two inner tubes don't work).

    However, on some days when I switch the amp on again, ALL 4 tubes LEDS stay off. Then sometimes when I swich the amp on again, the Infinium indicates correctly that the two inner tubes are 'dead'.

    Any ideas why sometimes all 3 leds stay off? Maybe I have to wait longer? Most of my practice sessions nowadays last about 15 minutes each, then I take a break.

    I am still in time to return it to Amazon and get a replacement, but the problem is, I am reluctant, I like the amp and waiting another 10 days to do ping pong with amazon is not high on my list. I just hope my 1960 is working correctly. It sounds great all the time, regardless, but the LEDS thing mentioned kind of makes me feel unsure

    Hopefully someone who has the competency to answer will do so. Thanks

    Hi Salvatore, welcome to the forum!

    Glad to hear that you are enjoying your new 1960 INFINIUM amplifier. These things sound incredible for the money right?

    In regards to your question - The first few minutes after the amp powers up are when the INFINIUM technology is taking fresh measurements to determine the health/bias of the tubes. It's not uncommon for the LEDs to flash or even stay on a few seconds. The LEDs should only be a concern if, after being powered on more then 5 minutes, the LED is lit and stays lit. After 5 minutes if the LEDs flash, it is the INFINIUM making adjustments to keep the tube optimal.

    It is very difficult for our INFINIUM technology to tell the difference between a missing tube and a tube with an open filament. In both cases there is no filament current and no plate current. The fact that the amp continues playing, sounds good, and the StandBy light on the front is not blinking all indicate the INFINIUM is accommodating for the missing tubes. So I would not be concerned if it sometimes lights the LEDs for the missing tubes, even if it could reliably tell they are definitely missing it cannot know you have pulled them on purpose.

    In that respect operating your amp this way will work just fine, but honestly it's not designed to be operated in this way so I wouldn't worry or get upset if it acts a little weird.

    One more thing worth mentioning, if you are removing two tubes from your 1960 INFINIUM then the impedance switch needs to be set to HALF of what the actual load is. So for example with a 160ohm cab the switch needs to be set to 8ohm. You did mention changing the impedance but weren't specific if you did that or not.

    Honestly if the amp is working/sounding fine otherwise (as it should) then you shouldn't have anything to worry about. Hope this helps put your cautions to rest, rock out!

    Hi Michael! Thank you so much for the fast reply. I am now even MORE impressed than I was already

    Yes I can say with no shadow of a doubt that my 1960 sounds fantastic consistently and continuously, regardless. My concern was not the leds staying on for the missing tubes...again, that would be -correct-, it's the Infinium saying 'hey these two tubes in the middle are dead (missing, in this case) ; my concern was about why sometimes the do NOT stay lit. In other words, the leds stay off for the tubes that are plugged in (unless they are faulty, which is not the case here), or they stay ON for the inner missing tubes (I use the 1960 with only the two outer tubes).

    But you know what? After some experimentation, it seem that the Infinium adjusts the bias every time I use a new volume setting. So what I do is turning the amp on, wait a little, turn off the standby switch, and after a few minutes the Infinium leds will show up correctly as they did when I first used the amp with only the two outer power tubes: the two outer leds stay off and the two inner ones are ON. So it seems that just wiggling the volume controls will cause the Infinium to readjust and operate the leds correctly.

    But yes I can understand the amp wasn't designed for two tubes to be pulled out (no amp is designed for that in mind, as it makes little sense from the point of view of the designer: if one wants lower power, they should buy a less powerful amp ). But anyways, I think it's all clear now, I get consistent results with the Infinium leds now. Yes I was using the impedance as you indicated, thanks for mentioning

    Anyways, I hope I wasn't too confusing. The amp sounds great regardless. The Infinium is truly extraordinary, I used to try to install bias pots on amps with fixed bias, because I like the hard distortion that fixed bias gives (but I like cathode bias amps too).

    So, anyways, the Bugera 1960 is a MONSTER. It is a beautiful amp, not just for sound, I mean even construction wise I see no difference in quality between my 1960 and, say, a Peavey tube amp. I have owned several Peavey amps, for example the Triumph and a Windsor head. I messed with amps for years and learned to do many mods, even replacing transformers, etc, so I am very hard to impress.

    The Bugera 1960 is incredible value for money! The fact that I am using mine, a + 100 watts tube amp, at half the power, means I can push the amp really hard and the transformers will probably last forever ( I used to blow several 50 watts head because I really push my amps hard, flat out etc).

    Effectively, now my amp is 'over-built'.

    I would recommend this great amp to anyone who wants a truly classic amp at the price of a decent digital amp (yuk!).

    Not only it sounds awesome, it is very well built, it is killer value for money, and it has the extraordinary Infinium circuit (honestly, I would have bought the amp for that alone).

    Bugera ROCKS. I am 120 per cent convinced. Thanks for the previous reply and have a great day.

    More Infiniun Questions

    Hello all! As opposed to starting a new thread I decided to continue this one because Salvatore took every word right out of my mouth as far as how I feel about the 1960 Infinium head! It's powerful, it's beautiful, and the mods (loop and mast vol) and modern tube tech is amazing to me!!! I am so in love with my 1960 that I also scored the 1990 head! Bugera tube amps are the best value on the planet!! (My 73 Marshall is in the closet!)
    I appreciate the power (first chord I hit before engaging the master volume almost stopped my heart!!) I can play festivals and arenas with this thing. However I love it sooo much I want to use it at home for practice as well!! Even with the Mast. vol. at minimum its still loud, so I bring it down more with my ME70 run thru the loop.. Fine and dandy.
    Now about my heat and power concerns at these low volumes.
    I too was considering pulling tubes, so as not be pumping 150 watts when it's not necessary, but i don't believe that is an option for me as I only have 4 ohm cabs, and pulling two tubes would make a 2 ohm setting my only (non available) option.. correct?
    My other question is that I've heard Volume is the only thing that cooks up the wattage anyway, so if my master volume is engaged and turned down then I'm not using excessive wattage anyway.. is that correct? If it is I wouldn't ever need to pull tubes. Great! I'm a fan of run it the way it was designed!
    The only reason I am concerned about the extra wattage is the extra heat I am guessing happens with 150 watt amps.
    (I know, I know, I'll probably get a G5 or G20 for the house, and save this Beast for live, but I'm addicted to it's sound!)
    In closing I have to say I am completely infatuated with your tube amps and I am going to collect as many models as I possibly can! Your excellent prices allow me that, where no one else does!
    Thanks for changing my life!

    Hi Daniel,

    Glad to hear you are enjoying the tone/value of your BUGERA Amps so much.

    I'll tell you that I'm confident removing tubes from your BUGERA Amplifier won't actually produce the results you desire. There is a common misconception that removing two tubes will drastically lower the volume. The thought I believe is that it's half the tubes so half the volume right? This is not the case, and is actually only about 3dB lower, so it won't dramatically reduce the volume like most people assume. Most humans need hear at least 10dB before they even start to perceive "half" volume so removing tubes won't really make that much of a difference. It's always better to play the amp as it's designed.

    The 1960 INFINIUM is a beast of an amp and is powerful enough to hold it's own in larger venues, that's what it's designed for and where it shines the most. The amp only puts out 150W when turned up all the way so honestly there's no harm in setting the gain on your amplifier the way you like and then just turning the volume down to bring it to a level that you deem acceptable for playing indoors. Doing so won't damage or overheat your amplifier.

    I'll agree that a smaller amp like the G5 or G20 would probably be better suited for playing at lower volumes, so it might be worth considering in your situation.

    Daniel, I agree with Michael, you don't need to do anything and it's always better to use the amp as designed and as it is, in other words, messing with it it's best avoided....as they say, if it ain't broke, don't fix it.

    I am doing the pulling tubes thing for other reasons, I am a bit of a nutter. But you don't need to concern yourself with heat or power....tube amps are built to withstand all the heat and power they produce. The Bugera does it even better as the Infinium regulates everything.

    Great amp, the 1960......20 years ago an amp like that would have costed a small fortune

    Believe it or not, I like it better than all the Marshalls I've had ! The Infinium thing still blows my mind..... I would be burning up tubes much quicker as I push my amps really hard

    Thanks for your feedback Mr C!! I agree that these Infinium heads are So awesome! My 73 Marshall is in the closet, as the Bugera is so much.. smarter! (loop; masterV; Infinium tech)
    The 1960 blew me away so well I sprang for the 1990, and needless to say, I am in Tube Tone Heaven!! That's my Rock amp, while the 1960 is my personal, do anything "swiss army knife" amplifier.. I run all my Digital preamps and modelers into the send of the FX loop and everything sounds so God like!!
    In the old days tube amps were fussier than your high maintenance girlfriend so I'm getting used to not worrying so much and just letting the amp burn!!
    Again, Thanks for your reply.
    I still think I wanna stack up a couple more of these before Bugera realizes they can easily sell these for twice as much!
    Best value on the planet!

    agree about everything, except about digital preamps or any digital stuff going through my amps....yuk....

    but to each their own

    I am not surprised you don't use your '73 Marshall....I too had many old Marshalls and the 1960 can proudly compare with any of them, soundwise. But the Infinium tech even surpasses them....
