Hello everyone,

I am trying to locate someone who knows is way around analog audio
circuitry. I am currently designing a Hi-Fi audio preamplifier digitally
controlled. I have no problem with the digital section, but I am quite
unsatisfied with the analog part. I have questions, but no one to answer
them. Please if you are able to help me and have the time to spare, your
input will be welcome. Let me know, and I will enter in contact with you at
your request.

And by the way,

Happy new year everybody !

If you have access to linear data books from National or
Signetics/Phillips, you'll find a lot of data sheets for audio op
amps like NE5534 with applications for audio preamp use - mixers, low
noise, RIAA equalization (remember turntables?). I'm kind of busy with my
new Web page right now, but if you're stuck, there's always time for a
fellow Canuck! E-mail me if you want.

Good luck,

Isaac

I have just been working on the analogue part of a digitally controlled
mixing console for one of my customers, so have met and hopefully solved
most of the problems - the first product is now working in Spain, and I
gather the client is very happy. In the past I have designed plenty of
high end hi-fi equipment, pre-amplifiers, power amplifiers etc. so
should be able to help. Problem is, time is a bit short right now, but
if you email me with your precise requirements I will do my best to help

I am looking to purchase a Urei/Universal Broadcast Peak Limiter
Model LA-2a,LA-3a,LA-4,1176 or the stereo version 1178.
I also need a complete set of knobs for the 1176 LN unit if
anyone could help me locate this or has any around the place.
If you can be of any service,I would appreciate hearing from you and
I have a decent budget for the purchase of a unit.
Thanks
