I am going to post a response I just got from Bob at Eurotubes about the retube options for the Bugera and what they can give. He definitely knows his stuff, and took a lot of time to be helpful


From Me:

My friend Jared Greene has been ordering tubes from you for a while and I have seen that you have always been fast, friendly, and very responsive. I am wanting to retube my Bugera 6260 combo amp, but I'm still trying to figure out what kind of tubes to put in it. If you haven't played one yet, its set up very similarly to a Peavey 5150. However, there are a couple changes. This amp has switchable bias, to where it can run EL34 or 6L6 type tubes. It also has a bias adjustment right on chassis, kinda like a Peavey XXX. I'm trying to figure out how to polish up the sound and smooth it out from the sound offered by the factory Sovteks. Here is what I'm hoping to acheive....I want to try to tame the preamp gain a little so that it drops some of the fizz and gives me a little more clean headroom. Then I want to get smoother, warmer highs and extended low end range, but I still wanna keep the cleans, because this amp offers very nice cleans (much nicer than the 5150 that I compared it to. I also tend to like an aggressive vintage type sound if that helps. I usually use OD pedals and a Compressor to add a bit of boost to the front end. The main power amp tubes I had been looking at were 6L6s and KT77's . I'm not really sure what will work better. So, I was hoping you could help set me on the right path. I know you know your stuff, and a lot of guys have recommended your help.



From Bob:

Yes I am familiar with these, the Bugera 6260 amps can use either a quad of 6L6's or EL34's, and five 12AX7's. Here is a brief description of the options.

The standard EL34 is just like the old European EL34's. These are a bit soft with a shallower low end and a smooth breakup with a nice crunch, a typical high quality EL34.

The JJ E34L's provide a deeper low end and are more aggressive and punchy than an EL34. The E34L is tighter with slightly more headroom and power with a more aggressive crunch, a very articulate British tone.

The JJ KT77 is tighter than an EL34 and they have a very deep low end extension with a nice sizzle in the top end that is not brittle. The clean tone is very fat and full and the crunch has more of a chunk to it and it's very punchy and more aggressive than a standard EL34, a great tube for rhythm and solo work.

So for a comparison the JJ 6L6GC's have about the same low end as the KT77's but are a cleaner tube with a later breakup and they are not as mid range heavy. More of a traditional Fender type tone. The 6L6GC's are a good way to go if you scoop your mids and these are a great tube for heavy rhythm and melodic drop tuned Metal.

These are adjustable bias amps and need to be biased! The most accurate way of doing this is using a bias probe under one of the power tubes. There are short bias probes available on Ebay and from several other sources including our own Eurotubes bias probe for 25.00 so it's a VERY cheap tool, very accurate and very easy to use.

We have been asked to do a bias video on these amps but it is so simple that we refer them to watching the Generic bias video we did on an 800 Marshall. The procedure is the same but when using a short bias probe you don't even have to take the amp out of the chassis. You ca see the video here, http://www.eurotubes.com/euro-Generic-Bias.htm You don't need to measure the plate voltage you can simply bias EL34's, KT77's or 6L6's between 34 to 40mA. Most players like them right at 36 to 38mA. The test points on the amp appear to be measuring a total plate current draw in Millivolts but we have found that itís not very accurate.

For the front end we usually use the JJ ECC83S's which sound very fat and full. I would use a balanced ECC83S in the phase splitter hole which is the preamp tube that's closest to the power tubes ( the one on the left when looking at the back of the amp ). This will eliminate any dead spots due to phase cancellation.

Weíve seen these come in with a mix of sovtek and chinese preís which arte pretty harsh and fuzzy so just changing to the JJ ECC83Sís with give you a warmer tone with less fuzz and better definition.

Using the Gold Pin JJ tubes would also be an option if you want the best of the best. The main difference with them is that they are smoother in the top end and a little richer in the mids. They are however expensive, the ECC83S standard Gold Pin tubes run 19.50 and the balanced ECC83S Gold Pin tubes run 22.00



So for what youíre looking for I would probably use a gold pin ECC83S in V1 which will get a great clean tone with a nice sparkle. You could drop down to an ECC81 for more headroom but this will sound a little sterol compared to the ECC83S. I think you would like the ECC83Sís in the rest of the positions but if you want to experiment with lowering the gain in the drive channels then you can use an ECC832 in V2 or V3 which will drop the gain about 40%. These run 12.00 each.

Awesome thread! Lots of good info so far! I am getting the 6262 head. It will be arriving next week. I also purchased the Bugera 4X12 cab for a quick fix. I will buy a Vader or Earcandy cab when I can afford it a few months down the line. This stock set up will have to do for now. I am excited I must admit. I haven't owned a tube amp for a long time.

You might be able to pick up an Avatar cab for a reasonable price.....I have run mine through an Avatar Cab with V30s and it sounds awesome

Good thread idea. I really like what I've heard from Bugera thus far, looking forward to trying on myself.

I used to play 4x12s all the time, until my travel for gigs got longer and longer. Now, I want something that fits well in a car with band mates gear. Plus loading a 4x12 in and out....well it'll make you strong, but if you start traveling you'll hate it.

It just goes to go how subjective tone is. The 333XL sounds like an amp twice its price, and I found the XL switch to really be useful for that ultra-saturated metal sound. Noise gate isn't the best, but it does remove a fair amount of hiss with no noticeable tonal degradation.

My "new" 5150 is better at some things, but the 333xl sounded better. but I would advise any buyer to really test it hard during the "return period". Mine worked great for almost a month and then died after I left it on Standby for an hour or so.

The "death" could've been a tube going, thus tripping the fuse. These amps need a good set of tubes to get the most from them.

The noise gate is like the built in noise gate on the XXX. It only removes a marginal amount of noise, and is pretty much just enough to keep the amp from going psycho.

Why was it necessary to leave your amp on stand by for an hour? Thats unnecessary tube burning

EDIT: Sorry, if i sound like a jerk, I'm not trying to com across as one. I'm really actually quite cuddly

Looking for a good tube amp for metal/metalcore/post hardcore. I liked the sound of the Peavey JSX i tried, but it was a lot of money =*(

Looks like i'll have to order them seperately then.

I suppose I could build the cab, might save a bit of cash and ill be able to use good speakers.

Do vintage 30's go well with the 333xl for metal?

Well, I changed the fuse and tubes still no glowy. It wasn't 'necessary" to leave it on Standby, but it really shouldn't hurt the amp. And the tubes had maybe 10 hours on them max. Believe me, it wasn't my fault.

I hope everyone else's works forever and I would recommend the amp. I am just saying someone wouldn't want it to go down out of the 30-day return period and have to wait to have it serviced.

I must admit, I sometimes worry about the long term life of my upcoming Bugera 6262 but my ultimate goal is to get a REAL tube amp in a year or so, a mesa, or marshall. I had a JCM 900 19 years ago I sure with I still had.

Bugera 6260...you can't go wrong my friend. Like I said in your other thread, the 6260 is great for hardcore/post hardcore etc. But I also use it for other stuff as well
