Lundahl LL7101, not much info about this one on site

LL7101.
There is not much info to be found on the Lundhal website about this trafo.
Can I use it as mic input ?; DI input, or to spice up my Ribbon mic ?

Ask Kevin Carter. He's very helpful with Lundahl info.

Why not just ask Lundahl?

Best regards,

I dare to say... Kevin is speedier!

I guess you've read
this already but just in case....

Also, for more info on various Lundahl trasformers check this website than klick on "Transformatoren" in the list on the left...

In a general word NO.
You must use that transformer in the exact circuit that it was designed.
It is a zero field transformer and it needs an op-amp to cancel out the fields so the core will not saturate.
There was an appnote from Analog devices but I cannot find it now.

I would say it is not like all the other transformers and I
would stay away.

Yes Kevin is faster and closer.

Too bad. I have around 50 or so of these

Dré,

why not try to revive the board where they come from? :?

Or Ebay them, for exchange for other more useful types :thumb:

Adrian was fastest of all and he wrote what I would have. :wink:

Use for Mixbus input transformers a'la Neumann V475?

(TDA1034=NE5534)

Jakob,

Just a question, is this more or less like a telefunken pre?
Or are we talking different beasts now?

Tony.

gyraf · May 2, 2005

The Neumann V475?

It's out of the same general series - specified by German broadcast - if that's what you mean..?

tony dB · May 2, 2005

indeed... i'm lurking to some Telefunkens, are these worth the typical Felekunten pres that seem to be prased into the highest sky by the telefunken adepts? :roll:

In that case I might be client for some of the trannies Dré offered... :wink:

Tony

andre tchmil · May 2, 2005

Tony.
The only Telefunkens worth to grap are : V72, V76 tube.
V676, V672, V276, V372 discrete. And even then be carefull you don't get the ANT types. These have nothing to do with the real stuff.

If someone is ineterested in these Lundhall trafo's , give me a call.
We can work something out :green:

I just recieved my new Lundahl Transformer catalog last Saurday. Second Edition. It is soooo much nicer than looking stuff up on the internet. All the pinouts are right there...

I put my name on the list at the AES show.

Ask Per for a catalog. Then you are set for life.

Well, at least until they come out with some new amorphous thingy that blows smoke rings around the 1538XL.
