What's with the 0-xxx on the inductors?

 

[NewYorkDave]

That's probably the value in Henries--at least at first glance, the values seem to make sense in the context of the circuit. For instance, 0.0159 would be 15.9mH.

Rob: That's a really cool EQ, a nice bridged-T implementation. Do you know anything about the input/output coupling transformers? Is the EQ 600 ohm in and out?

 

[Bauman]

Many thanks to Rob and the Boogie Man!

Yes, so much great info.

I see that you all have formed a master plan, and that your goal is to boggle my mind with so much information that in no way shape or form will I be able to keep up.

My DIY folder keeps growing and growing, but my ability to finsish projects, get up to speed on all things audio electronic, and digest all that gets posted can not keep pace.

I feel like a sinking ship. But at least I'm a happy sinking ship :grin:

Sorry, I only have the diagram & no other info.

Nice stuff!
BTW, in UREI 500 hf/lf sections done around three switchable t-pads, but arranged the way eq attenuation is just 10 db.
One problem is...they used 7-pole 12-positions switches...
bbc eq seems more diy'able)

Cool stuff indeed, thank you mr O'Boogie!

Thanks a bunch Winston!

Rob, where does that eq come from?? I may have some other info for this in the pile..

 

[Rob Flinn]

Rob, where does that eq come from??

I was lent some information by a friend & this was part of it.

 

[tommytones]

If it's too sensitive to talk about in the open, pm me. If you can tell me what console, truck, studio, etc... this comes from, I can look through the docs we have here and see if I can't dig up some other information.

 

[Rob Flinn]

Its not too sensitive to talk about. I just don`t have any more information on it ! It just came as a diagram. Sorry. If you can did up any more info I would be interested to see it.

 

[tommytones]

cool. I'll see what I can find....

 

[NewYorkDave]

The Urei 500 sounds interesting. Anyone have a schematic or other documentation?
