Vintage Tung-Sol 12AX7 Long Plates
adam79
long plates either have a halo or D getter. I've read alot of positive
reviews about the ones with D Getter, but haven't found much info about
the halo getter versions. Anyone that has experience with the two have
any comments (comparing the two)?
Also, I've read alot of positive reviews about the current production
Tung-Sols (regular plate length), especially when in the v1 position of
a high gain amp. How do these compare with the vintage ones mentioned above?
Thanks,
-Adam

What is your point ?

The old Tung Sols are pretty good - IF...
...you can find one that's not too microphonic
to use in a guitar amplifier. Like most of the
large-plate 12AX7s from the 50s and 60s,
the old Tung-Sols weren't really designed
for high-gain audio. Little niceties like low
H-K leakage weren't a big consideration
when designing a tube that was destined
for use in a table radio or a TV set...or even
in guitar amplifiers, which weren't "high-gain"
at the time. So, a good one will indeed be
very good, but the ones which will operate
*satisfactorily* in a guitar amp - especially
a combo amp - are few and far between.
Excessive microphony is very common with
these or any other long-plate 12AX7/7025s
from that time period. They'll be at their best
in old Fenders, Gibsons, etc. Put one in the
gain hole of a Mesa Triple Rec and it'll shriek
like a train whistle...unless, as I stated above,
you're lucky enough to find one that is - by
1950s-1960s specs - exceptional.
The currently produced Tung-Sol is a different
animal entirely. First, it has no relation - NONE
WHATSOEVER - to the old design. It's a modern
tube with a vintage logo on it, and is in no
way a "re-issue" or a copy of any 12AX7 the
original Tung-Sol company ever made. (The
excellent Reflektor/Tung-Sol 5881, on the other
hand, IS a reproduction of the original, and a
good one.)
That said, it's one of the best currently-produced
12AX7s on the planet, and the fact that it was
designed *specifically* for use in guitar amplifiers
is evident in its stellar performance in that application.
The engineers were tasked with producing a tube with
a very low noise floor, low H-K leakage, low microphony
and low rattle, and specifically designed to operate
inside a metal can, upside-down and six inches from
a screaming speaker. Yes, there have been good
batches, killer batches, and rotten ones, so buying
from an outfit which actually listens to them as part
of the testing process is highly recommended. (See
my sig for details.) In my experience, only the legendary
Beijing Silver Special has a lower noise floor among
any of the mass-produced un-hand-selected product
that was/is available in production quantities. (Limited-
run audiosnob stuff, like the Telefunken E803CC and
whatnot, will have a lower noise floor. Check pricing
on those. And it's still a crapshoot on the microphony,
which, after all, doesn't really come into play in an
audiophool system, which sits on the shelf and is
operated at civilized listening levels. YMMV) The
Silver Special ain't coming back; the machines on
which it was produced were destroyed by the commies
when the plant was shut down. (A half-assed copy
is currently produced by Shuguang; it's, well...half-assed.)
Right about here is where the Glass Snobs are going to
start squealing about how I only hype the stuff I sell.
Fair enough. And my reply is, I sell the stuff I LIKE,
because I know other folks are going to like it, too.
And just to set the record straight, I have a shitload
of original-production Tung-Sol 12AX7s (and 12AU7s,
and if you want to engage Full Glass Snobbery, 6550s)
and they're for sale. They won't work for shit in most
modern high-gain amps, and I'll tell you that when you
order them. I am, after all, a businessman, and I'll
certainly take your money whether you take my advice
or not. BTW - none of those are for sale to assholes...
you know who you are.
OK, bitches - start squealin'.

The input stage of a 5E3 has 100K plate resistors.
Two cathodes (in the same triode) are paralleled
on an 820-ohm resistor bypassed with a 25uF
electrolytic. A 1-meg grid leak resistor on each
grid. This is *identical* to most Blackface input
circuits, although 1K5 resistors are often used
on single cathodes.
However, the schematic specifies a 12AY7 for
the first gain stage on the 5E3. The mu factor
for a 12AX7 (Blackface) is 100. The mu factor
for a 12AY7 (Tweed) is 44.
Someone here is certainly stupid. Must be this guy:
"Well, yeah, I gotta admit that I did indeed fuck yer mom up
the ass when she was 14; the legal age in Arkansas was
15 at the time, but she lied. She fed me some song and
dance about how she'd been constipated for a week and
really needed to get reamed, and I figured what the hell...
even some gap-toothed whore's ass was better than
jacking off, right? So I did the deed, and sure enough - two
days later she took a massive shit, and it posts to AGA as
'Dienazi' now."
Oh, well...at least you weren't so dim you
weren't able to correctly interpret my invitation
to start squealin' with the rest of the bitches.
Good dog.

well I go with what my ear hears and what gigging reliability I have experienced
when it comes to tubes.
I can tell you that the current production Tungsol 12ax7's I am using
are bullet proof. And they have a nice gain character to them in the
Fender Prosonic head I use. They are quiet (I use them in the V1 and V2)
and put out a minimum of hiss and just have the front end of the amp sound good.
I use Svetlana current production tubes in the rest of the preamps and phase inverter.
However I do have a stash of current production Tungsols (in case the next batches
in future years suck - I keep a bunch from a good current production batch).
so if the Svet's give up the ghost then I'll just replace them with the Tungsols.
The tungsols are really excellent 12ax7 tubes.
And - I also have recent production set of Tung Sol 'short bottle' 6L6's
in the Prosonic and personally they are the best recent/current production
6L6 power tubes that I have ever used. So the 'short bottle' TungSol 6L6's
are my standard when it comes to current production 6L6 bottles. Excellent.
Better than any long bottles or any other 6L6's out there today.
And they last and last... never have had a problem with them and I gig
my amp around a lot. And they sound great and saturate nicely.

Hey LV,
How to get on your tubes and parts mailing list? I have tried to re-subscribe via your Prodigy account over the past few years but so far I have received nothing.
And your nebsnow.com web site seemed to have gone down, too?
Anyhow, please let me know the subscription instructions.
TIA.

I usually harvest the addies from that account every three or four months.
That address is so widely disseminated it gets spammed
like you wouldn't believe.

Yeah, nebsnow (New England Business Services) went tits-up.
I'm looking at hosting companies. Problem is,
I'm a one-man show, and shit like that takes

Hey LV,
Thanks for the prompt reply. My newsreader's email address is fake, due to spam and whatnot.
So, does that mean I can give your Prodigy address another try by sending a blank email with the words "Spam Me" in the subject header? I'll add "(the guy from AGA)" in the subject header, hopefully that might distinguish my email when you scan your inbox.
Too bad about the website, I was hoping there would be subscription instructions there. Reckon you probably prefer to spend more time hitting some Hammond keys to PC keys.
Cheers!
Lord Valve
Sure, go ahead. I'll check it later today.

Anyways, thanks to the couple people that responded to my question; good
info. As far as Lord Valve goes, I think I might have bought an old
stock Brimar 12ax7 from you on eBay. It sounds killer in the v1 slot of
my Peavey VTM-120. I assume that the VTM-120 would be considered one of
the "high-gain modern amps" that someone was referring to, right?

Nope, not me...I don't sell on e-bay.

one that mentioned long plates working better w/ vintage amps (i.e.
Fender and Marshall) rather than modern high gain amps (like a Dual
Rec). The Peavey VTM-120 would fall into the "modern high gain amp"
category, right?
