What are the eouropean equivalent?
5881.

But those distinctions are pretty much gone these days. They make
6L6's in Europe and China now.

Wrong wanker boy. The 5881 is a ruggedized equivalent of the 6L6GB
originally developed by Tung-Sol for the US military. Claude's post is
accurate.

Esther-NOT-A-Lo0n's motto is:

"No Ankle Left Un-Humped"

The OP wanted Euro equivalents, so I Googled for him. :^)

I'm pretty sure that the only EL37s are antique Mullards
and that modern KT66 are 6L6 innards in a bigger bottle.

5881 *is* the US Military designation.

The URL I posted describes the differences...

So, where does a 7581A fit in? (You know, besides in an amp.)

From

Type KT-66/7581 Tubes

The 7581/A tube is an industrial strength version
of the 6L6GC which is also said to be the American
equivalent to the British KT-66. The ratings 7581
are roughly the same as the 6L6GC while the 7581A
has higher ratings. The 7581 has a plate voltage
rating of 500 V--35 watts (5 watts more than the
6L6GC) and a screen rating of 450V--5 watts.

Sort of.

WARNING: The KT66 has a 41% higher heater current draw than a 7581A.
That may be enough to burn up a weak power transformer that was
designed for a 6L6GC.

The tone of a KT66 can be quite different from a 6L6GC or 7581A, too.

7581A will work just fine in any amp designed for 6L6GC's.

Often, you will see tubes marked "6L6GC" and "7581A" that have
identical internal construction. These are, in fact, the same type of
tube.

Theoretically, the 7581A is a higher wattage, higher plate voltage
tube. But not always in practice. Depends on the manufacturer.

As I posted in response to Claude, his response was not quite accurate.
I said:

"Warning: KT66 is not an exact equivalent to 6L6. It pulls 41% more
heater current (1.27A versus 0.9A for the 6L6GC). That may be enough
to kill off some weaker power transformers, especially in a push-pull
amp. If your PT is up to it, though, the KT66 has the same pinout as
the 6L6.

The EL37 pulls even more heater current (1.4A). Same pinout as 6L6."

The 5881 *IS* a 6L6 type. My post was accurate.

And once more, Wanker-Boy Giblets goes down in flames!

(Nice try, though.)

Apparently, you don't know what equivalent means. To have an
equivalent does not mean that they are duplicates of each other.
That's like saying for Ford or Chrysler to have an equivalent motor to
the Chevy small block, they would actually have to build Chevy small
blocks, which of course is not the case.

Apparently, you lack both technical knowledge *and* a dictionary,
Giblets.

"Equivalent" in the tube world means that two tubes are interchangeable
in the same circuit. Like 12AX7 and ECC83. Interchangeable, without
burning up becuase the voltages are too high.

Ford would have to make an engine that would fit, unmodified, into a
Chevy, idiot. Analogy escapes you as well.

Let's consider the only place in the world where the 5881 is currently
made, shall we, Giblets? The only current production 5881 tubes are
made in (drumroll please...) Russia. Which is in (another drumroll...)
Europe. Making it a European tube. And a drop-in 6L6 equivalent to
boot.

Learning anything, Wanker Girl?

As I told your mentally challenged friend, Giblets, the only current
production 5881 tubes are made in Europe (Russia). The old Euro vs. US
designation doesn't mean jack shit when it comes to 6L6's.

When a poster asks a question about a "6L6 equivalent" in a guitar amp
forum, he's talking about a 6L6GC. And as Marc mentioned, there isn't
an exact old-Euro equivalent. So, understanding what the poster wants,
I cut to the chase and tell him what he needs to know.

Any jackass can look a tube data sheet. Like this one:

http://tdsl.duncanamps.com/show.php?des=6L6GC

But it takes a brain to read it and notice that the similar old-Euro
tubes have lower plate voltage specs and are therefore not 6L6GC
equivalents.

You're as dumb as you are dishonest, Davy. No surprise there!

Oh, I don't know, Dave. You seem to be a moron. And I'd say reality
bears that out.

How's your business these days, now that you've revealed to the public
that you're out to rip them off?

Now THERE'S your laughter!

P.S. To the OP: If you want a tube that will work in your amp, ignore
these two dumbasses and listen to what I said.

Did something happen over the

If you want to be mad at someone,
call up Mike Mathews(sp?) for starters.
He started this bizarro, naming convention
issue.... The only thing we've really been
sure of over the last 10 or so years is that
it's glass & contains some kind of internal
structures... ;)

Which leads me to the next question: has anyone
tried any of the new(er) Svetlana 12AX7s? (Not the
old Svet 12AX7 (SED/Flying C/St. Petersburg tube),
but the Reflektor made version. Dr. Z recently turned
me onto them. Nice, I think. They look alot like the
new Tung-Sol. However, no one knows anything for
certain...

have a nice fight,

He didn't ask for a tube that would work in his amp. He asked "What
are the eouropean equivalent?" for "6L6 tubes", to which you answered
quite succinctly: "5881". You can sidestep all you want, anklebiter,
but the fact is you're wrong.



Hi BK,

You know me, I'm cool with just about everyone, until they post
unsubstantiated lies (ie; total bullshit) about me.

What do you think when you see an ebay item listed "as-is"?
Can you return it? (that's why the E-sock is nipping my heels, here)

Not really. Delivered two amps. Picked up four more. Too damn busy to

I think he just carried on what Sovtek started with the XYZ, WA, & WB

I'm not mad at anyone, but the anonymous E-sock tends to fly off the

To begin with, 6L6 and 6L6GC aren't even equivalents.

The following are considered "close or identical" foreign equivalent
designations for a true 6L6:

CV1286
CV1947
CV1948

But I do NOT find a true equivalent european designation for a 6L6GC.
