anyone tried el34s in a tweaker?

Re: anyone tried el34s in a tweaker?

I've very lost here...I gave my thoughts and backed it up with numbers, one of which was correct one of which was off my .01 amps...

I'm out of here, this thread has gone seriously off track.

I am sorry if any of it was my fault but I was just trying to help someone and hopefully save his amp from a slow death for what seemed like no good reason.

Re: anyone tried el34s in a tweaker?

I did supply numbers in post 12, I said 6V6's pull about a half amp (it's .49 if you want to be exact) and EL34's draw about an amp and a half (it is exactly 1.5 amps)...

I never once said in this thread or any other "because I said so" and never would...

I don't talk down to people either and I don't speak when I don't know things for sure.

I don't know what your issue with me is but it's clear you have one so let's just agree to disagree and let it go...no need to turn the forum into a pissing contest...

Coming from the guy who said that, and I quote:

The lines between all these tube types are all blurred these days anyway not to mention many new makers build tubes and label them wrong anyway.

sorry, man. The amps contain lethal voltages, and people need to be aware of this. Also, specifications are very important when we are changing the way things operate, or the tube types. Generally, there is a little engineered wiggle room, but there are important differences between the tube types that need to be addressed. What I would try in a 6V6GT Tweaker would be a pair of Yellow Jackets and EL84's or 6L6GC's. Those would change the tone and be within the limits of the power supply, except for changing the bias voltage range for the 6L6GC. They need about 18-20 volts more negative voltage.

Taking quotes from another thread about another topic doesn't really hold much water...it is clear you are just trying to stir the pot here...

Sorry I even opened the thread again...should have known better.

Stirring a pot with no water in it? Sounds crazy to me.

Stirring a pot with no water in it?

Other fluids are available.

Re: anyone tried el34s in a tweaker?

If someone called customer service and got an answer then the issue is solved... not to mention I and 6 others sat in a room with Bruce Egnater for 2 days building amps and this very question came up... No need for all this goblygook and pee contests. I can pee further anyway.

Listen here man...whatever you do don't confuse these guys with the facts!!!

See, you're not getting that we were in agreement on this issue in the first place. I just went at it from the specs, and from what convention is in guitar amp circuits. No pissing contest, here, at least not from me. But remember this, my soldering iron is bigger.

Re: anyone tried el34s in a tweaker?

Just called Egnater Tech Support (very nice guys BTW) they told me that since the amp is cathode biased that EL34's will run in the amp BUT they do NOT support it and warned me that the added current draw and extra heat the amp will produce that it can damage the amp...

This is odd, because I own both the combo (Tweaker 15) and the Head/Cabinet (Tweaker 15) and I actually received an e-mail that states clearly that EL34 can be used in the Tweaker 15.

Here is a photo of the combo and head/cabinet. (Note the iPB-10 and 4CM method is used with the head.cabinet)

The head has EL34’s installed in it, since this last Saturday - tone is different with an apparent difference in head room and cruncher tone. But not exactly a Marshall tone.



TGWIF do you actually own either of these amps?

I also tried to install a set of GEC KT-66 tubes but there is no way that the GEC KT-66 tubes will fit into the head cabinet.

So I installed outside of the cabinet, and played that way...

The GEC KT-66 tubes sound very nice with a soulful and distinct mid-range tone and none of the EL34 harshness, but also the KT-66 do not have the buttery tone of the 6V6 tubes… Next try is 6550’s….

A different selection on preamp tube are on order….

TWEAK it baby!

Re: anyone tried el34s in a tweaker?

Now Larry has to get involved...read my post, the guys at Egnater were very clear...the Tweaker CAN run with EL34 but due to the added heat and current issues they do not suggest it and will not support it.

I don't understand what is not clear about that...

As for the do I own the amp question, I don't see how it matters...a good friend of mine has one, he bought it on my say so, I have used it many times and am very familiar with the amp and in fact am fact am familiar with all the Tweaker amps but no, I do not currently own one myself.

Some facts!

1) TGWIF does not own this product. (As usual!)

2) He claims without proof that the manufacturer doesn’t support using EL34’s

3) Oh, but a friend has one that he used many times….

B) There are a lot of users on the gear page that use EL34’s n the Tweaker 15.

C) It’s a tweaker - for pete’s sake!

(Face palm). I'm going to just send Bruce over here.

Re: anyone tried el34s in a tweaker?

Please do.

IMO, a hyperlink to the .pdf version of the Tweaker owner's manual would be pretty helpful.

Thank you and good night.

Re: anyone tried el34s in a tweaker?

Here is the info from Bob at Eurotubes, well the power tube info anyway.

So yes, we have done a variety of tubes for these and here are most of the options for you. The Egnater Tweaker comes with a pair of 6V6’s and when we auditioned these amps at the 2010 NAMM show Bruce was kind enough to answer our questions about bias ands tube swaps. The amp is cathode biased with no adjustment so it will also accommodate EL34’s, E34L’s, KT77’s and 6L6GC’s.

The JJ 6V6's are a very full and round sounding tube and when pushed at higher volumes are a little crunchier in the mid and upper mids than a 6L6 is.

The standard JJ 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. Standard EL34 tubes are not real tight and are known for a slightly looser and more vintage feel.

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's have even a bit more low end extension than the JJ E34L's and they have a nice sizzle in the top end that is not brittle. The clean tone is very fat and full and the crunch at loud volumes has more of a chunk to it and it's very punchy but not quite as aggressive as the E34L, a great tube for rhythm and solo work if you like the pushed mid and upper mid tone that all EL34 type tubes have.

So for a comparison the JJ 6L6GC's have a little more low end than 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. They will also give the fattest and most linear full spectrum sound of all the small bottle octal tubes which also makes them a great tube for just about anything from Rock to Jazz to Country.

More flaming?

Why does he claim to have invented fire?

Re: anyone tried el34s in a tweaker?

Probably over-compensating for something. There is another character on the forum who claims to have invented the wheel.

Thank you for your last post. For me, the single most critical detail is the FIXED BIAS. Armed with this information, TGWIF's post make more sense. Cross-referencing with valve specifications should provide some clue as to suitability and life expectancy.

You can call egnater just as I did and get the same answer I did...

I have not ever said that you can not put EL34's in the amp and I never said that it will not run, in fact you can and it will I simply said that it will generate far more heat than normal and Egnater does not support that change as the added heat can damage the amp.

Why is this so damn hard to follow???

As for not owning the amp I don't have to own the amp myself to be able to ask questions about it, take advise from tech support or know whats going on with something...like the man said, you don't need to be a weather man to know which way the wind blows...

I'm not making up for anything...

Frankly I don't give a **** either way what BR (or anyone else) does with his (their) Tweaker...I was just trying to give a little help since if you follow BR's amp posts he owns several and all of them or at least most of them are in some state of needing repair...

Just let it go bro. Not even worth the effort or frustration.
