WTB: Western Electric 111C or similar audio transformers
« on: June 26, 2019, 07:57:22 PM »
I want to build a passive "color box" kind of thing. Therefore looking to find some usable transformers for this project.
If you have something similar or more common to offer, let me know  :)

WE111C are a wrong and expensive choice for this.  Despite much internet folklore they are all but invisible in the audio path, and I've spent months with them available in a mastering chain hitting them at all levels on many genres with great converters.

I'm guessing you could get them to misbehave more by using not ideal out/in impedances but I would look elsewhere.

For good value I liked what the cheaper steel Cinemags did, a little fluffy for mastering but fun in a recording and mixing scenario.

Yep, they do a thing but it's pretty subtle.  Not what I think of when I think 'color box'.  Now those HS-56/66 as used on Pultecs, those things are a fluffy color box.

thanks for the clarification. I wasn't aware of that!
What cinemags are you refering to?

I would love to try them one day but unfortunately they aren't low-budget although the sowter 3603 sounds like a possible alternative ?

would these also work for that purpose?

Probably, but no telling what response  or headroom is there, they look pretty small.   That vendor is chronically overpriced on everything too; it's one thing if you can say WHAT you're selling, but generally there's no info.  .

I went for two utc A20. If you ever built something similar, how does your unit/box look?

I want with two Stancor WF-30s, which are pretty much the same as your utc's.  I used the little box in the attached pic.

Looking great :) First time i hear about the wf30!
Haven't seen rack units yet. Are boxes more practical?

I wish I would have put mine in a 1u rack with my passive monitor controller and direct box transformers to save space, but most that I've seen have been in little boxes like mine. 

These transformers make almost every individual source sound better when tracking.

Good to hear! Really excited to try this out. :)

yeah! thanks. Already checked it out  :)
Does it make sense to use a pot when only using one transformer per channel?

Yes, if you want to send a hot signal to saturate the xfmr.  A Daven attenuator is made for specific impedances -600/600 in this case.  You can use a pot after the xfmr, but it may change the response.
