I have a Bugera 333xl 120w combo. I was wondering if I can take some tubes out in order to cut the power? I need very little power for the small practice room we have and want to save the tubes if possible. I really don't want to risk causing damage to anything. I appreciate any help you can give.

Re: Half the power in amp
You can remove a pair of the power tubes, but you'll be dropping from 120 watts to 60 watts, which really isn't that much quieter.
The 333XL is a master volume amp. You could just turn down the volume.Nope...

Re: Half the power in amp
By pulling two tubes, doesn't that change the impedance as well? Don't quote me on that, but I believe I've read that before.My songs....enjoy! (hopefully )

or for older stuff too, but slower downloads

But, like I said... Master volume? Easy as a knob turn. I rehearse just fine with my rehearsal studio's DSL100 at about 2.5 on the master.
If you want power tube distortion, you're going to need an attenuator of some form so that you don't blast your face off.Nope...

Re: Half the power in amp
pulling 2 tubes to save wear on the other 2 is a bad idea... No one here mentioned you HAVE To pull either the middle 2 or the outside 2... you cannot pull the 2 on the left or right and you have to halve the ohms on the back of the amp.
If you run the amp this way for some time and you put the other 2 tubes back in the wear will be uneven. The old tubes will draw less current than the new. At best the amp will be a little more noisy from the imbalance. At worst it if the imbalance is severe enough it can cause some weird surging in the sound issues.
Let the tubes wear as a set. Even an attenuator is an imperfect solution if you want to save wear on your tubes. An attenuator sound like pewp if you crank an amp to 10 and then dial it down to conversation levels. Its good if you need to run your amp on 5 but sound like its on 3. But it will still wear the tubes like the amp is on 5.
If you need something very quiet for your practice space I would suggest a different amp. That way you can save your tube amp for when it counts."It keeps you fit - the alcohol, nasty women, sweat on stage, bad food - it's all very good for you." -Bon Scott

I would've touched upon these points, but I really think he should just turn the master down. LOL

I mentioned the other stuff cause he wanted to save wear on his tubes. In reality low master volume settings will save his tubes."It keeps you fit - the alcohol, nasty women, sweat on stage, bad food - it's all very good for you." -Bon Scott

Re: Half the power in amp
I stumbled across this Premier Guitar article on pulling tubes from your amp: http://www.premierguitar.com/article...o-reduce-power . Interestingly, it mentions that you can pull both the outer, both the inner, or pull alternating tubes with no problem.Join me in the fight against muscular atrophy!
