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.

Cheers,
Bas

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,

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.

Cheers,

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.

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?
