Neumann V473

[chriss]

Hi there,

I was offered a set of V473 C power-amps with 4 watts for an o.k. price. The seller mentioned it could be used as a headphone-amp, since 4 watts is not that much for speaker-use. Does anyone have information on this and any information on the cards in general? I couldn't find any helpful info on the whole web...
What would I have to do to use a common power-amp for headphone use anyway? Power-soak? impedance-matching? And if so - how?

thanks

Chris

Shouldn't need any changes - just use as-is..

The voltage levels of a 4W/8Ohm amplifier is already in the right range for most headphones.

Is there any Neumann stuff known to mankind without TXs ? :shock:

Sadly - yes.

..nearly everything manufactured after 1990.

@ [silent:arts] !
To be honest: I was expecting this kind of reply from you :grin: Thank you very much, I love your collection...

Yes, there is a special name for that: TLM (Transformer-LESS-Microphone)... Not too bad in my opinion...

Ah, I see. My original slight amazement at Neumann-stuff was that the various older circuits floating around here all have lots of TXs or at least 'difficult' ones, from a DIY-standpoint. Which gave me the feeling that Neumann felt inclined to have at least a certain amount of TXs per box, company-policy. (That's nonsense of course)

Not at all... Try www.haufe-uebertrager.de or www.pikatron.de for any neumann transformer.

Hey, I got a pair of V473 but cannot find any info. I'm happy to find this but It's expired. :-\
