Hi community,

I am on the way to develop a huge all tube mixer, for a huge all tube studio : http://kerwax.org/studio/

https://www.facebook.com/studiokerwax?fref=ts

Kerwax is one of the biggest all vintage gear in europ and the world, and i work for them as maintenance engineer.

Their demand is totally fool :

32 tracks mixer, 8 busses (stereo) and 12 aux sends ...

i need for this job one precise audio input transformer

Primary 1 coil 200 (600) ohms / +6 dB capable / 20Hz - 20 KHz

Secondaries :
3 (or 4) coils 200 (600) ohms / +6 dB capable / 20Hz - 20 KHz

i already got one beyerdynamic here that does the job,
it's an old ('90) very good and top quality trafo ...

it's ref is beyerdynamic TR/BV 351900029

i need 40 of them,

but i also can buy its equivalent if avaible,

maybe you, germans particularly, know where i can find some,

thx for reading and maybe help

don't know about the genuine beyer transformers, but if you need 40, it should be easy to get them custom wound. i know that Omynee Industries in Orange, CA(near where i used to work) can do this. i suspect it should be easier in Europe to find someone who would wind 40 to your spec.

contact brian sowter send him the specs and he will custom wind the transformers for you to you data details

has a good turn around for custom projects

its what im using on my custom tube mixer

[garyb]

yes, he's a well known guy.

THX gary and jhulk

i know there are few people that can do that and i am also looking and asking for prices here in France
but it expensive ...
lundhal has got one that may match @ 150 euros ...

beyerdynamic is is real good ratio price vs quality, and in germany you can find lots of old stocks of them ... i already bought many on eBay.de

anyway thx again for caring

if you ask brian he might already have a equivelent

the ones he makes me usually are £45-60 depending on quantity

also try carnhill www.audiomaintenance.com can give you the equivalent
