Hi,
Remember the WE310A as used as the input on the WE91 300B amplifier?
Svetlana has just brought the Russian copy of this valve back into production.
Just thought I'd let you all know.
Cheers, 😉

the theater amp 🙂
i babysat an angela 91 amp (which is based on the original circuit) months ago, and though it sounds nice, i find it slow and lacking in dynamics.
with the 310A driver, does it improve?

Hi Frank...
This tube must be very scarce? Since I can't even find a datasheet on the 310a...
All TDSL says is that it is a pentode? And it lists some equivalent.

Bas

Hi,
It does, the penthode DHT recipe was well known by the WECO engineers of yesteryore.
Bas,
It was very scarce and went "La Maison De L'Audiophile" released the cicrcuit diagrams prices went through the roof. 500 to 800 USD for an original WE was not uncommon.
Not to mention what the Japanese were willing to fork out for it...
The diagram:
L'AUDIOPHILE VERSION
The 310A datasheet:
WE310 A
Note, the WE310B is no good here.
EDIT: If not mistaken the anode cap is the same as for the 807, check before you buy though...
Cheers,😉

Hi Frank,
Thanks very much for the links...
What would the price be? Is there any info on that yet?

Hi,
No idea, I get them at wholesale quantities...(50+)
I guess you'll see them soon at around Euro 30 to 40?
If you like some let me know and I'll put some aside.😎

Still in the valve biz , Frank ? I always thought you were holed up in the boring world of IT like me

Hi,
Unintentionally...
I suppose you know what it's like, people will always ask for this or that because they assume you'll always find it.😉
Which is another good excuse...😀
Either way I just offered to help out, you know.
Cheers,😉

It
IT : It's provided me with a job rather than a career . Been there seen it , got promoted , moved up , moved around , sat in boring service review meetings when I could have been in the pub , had rocks thrown at me at 2am in the morning by people who don't realise what the time is in Europe and I'm back where I was 7 years ago but without customers throwing rocks and zero stress . Just the way I like it now , pub is 50 metres away , no-one really bothers me , dealing with helpdesks and 'centres of excellence' who don't have a scooby-doo what they're doing 🙂 It's fun having 15 years experience , all everyone knows how to do these days is to start a conference call
Anyway I'll drop you a mail at some point

frank,
since you've got the tubes, have you compared the Svet 310A to the original WE310A? can you tell us about your observations?
furthermore, how is called by Svetlana? still 310A?

another option 328A
One other thing you can try is a 328A. Its the same tube but with a 7.5 filament isntead of the 10v filament in the 310A. I once gathered the parts to build a WE91a amp but substituted the 328A because its much cheaper.
By the way datasheets for many WE tubes (including the 310A and the 328A) can be found here:

Hi,
The only thing I can tell you is that back in the early Nineties, when the WE310 A was still "available", this was of course the preferred choice by the WE 91 fans.
Later on on we had to resort to STC equivalents ( STC 4310 A if I recall correctly) and after that the USSR equivalent was sold to customers.
As far as sonic differences go between the original WE and current Svetlana, I honestly don't know.
I can only hope they'll be as good as the WEs.
Another alternative to the WE 91 L'Audiophile is the Zaika 300B which uses the very much more available metal 6SJ7.
While this is a nice penthode, I thoroughly dislike all full metal jackets...😀
Looking forward to it.😎

What is the Svetlana part #
Would like to find out more about this tube, I e-mailed New Sensor in the US to see if they plan on carrying the tube.

Hi,
Mike and all concerned,
This afternoon I received an e-mail from my supplier stating that these tubes are NOS.
So, not a new production run as they let me to believe at first.
Bas, take note pls: after these are gone I can't guarantee any further availability.
