Triad A11 J reissue transformers

How much was the price for those?

Did you buy them direct from Triad?

Thanks

I paid $200 each for them.
I was not able to order them directly, so I ordered them from: https://www.onlinecomponents.com/en/

This is the first I've seen the reissue A-11J "in the wild."

Encouraging to hear they're performing well for you! And if they're as-advertised, $200 is steep but not ridiculous (or at least more affordable than the vintage originals).

I agree.
It’s certainly a bit more than I was hoping to spend on this project but because I was trying to create an authentic Wolfbox, I splurged. There was no way I could even consider the vintage prices on eBay.

I recently made another passive DI using the Sowter 1585, which is allegedly similar to this, but I did not find that they sounded the same at all. Although it sounds really good and it was my favorite until I created this one, the 1585 did not give me the same result when it came to the complex harmonics. Now I will have to go back and compare this with some of my others.

I’m about to make a straight passive DI using a Crimson CTA 11. I’m sure I will post when it’s done.

Ouch!!!!
That’s very expensive just for a passive DI

Thanks for letting us know

I can’t speak to the reissued product, but the old A-11J really does seem to do something unique as a bass DI (also as a guitar DI

Would love to listen some comparison files of an A-11J DI and an Active DI with guitar em bass.

Maybe someone can record some parts, that would be great

I’d love to do that; sadly I’m out of town for a few months and away from my studio (and gear)

I am thinking of building this box with a CAPI CA11 transformer. Would this work and where would I find a wiring diagram? I am not new to soldering but am new to reading schematics etc.

If you’re in the US, Digikey has them for about $140 which is not bad: https://www.digikey.com/en/products...i5V5Fb_GLCxqvnOxD5adytPAUkgNaJsUaAh1sEALw_wcB

I received one last night and they look exactly like the old J series… let’s hope they sound as great!

 

[soapfoot]

That is not too bad! Let us know your impressions!

that is a much better price than I paid. I already know that they sound really sweet. I have no ability to compare to a vintage one but so far, it’s my favorite sounding passive DI in the building.

I already regret not getting two to make a stereo DI!

I had to. I have so many people coming in here with old synths.

One day I’d love to figure out how to gather some data on exactly *what* the old A-11J does that makes it work so well for bass DI

L091c: Are you sure that the A-11J and the XLR connector are wired up correctly? I could be -- VERY -- wrong here, but it seems to me that the secondary connections should be swapped, with the RED wire going to XLR--Pin-2 instead. Or, maybe it's just me!!!

I agree to maintain "absolute polarity". Green (primary) and Red (secondary) correspond with each other.

Of course, the original Wolf was designed decades ago when "XLR pin 3 was hot" in many USA audio systems.

I modified my old Wolfbox DI that had a UTC 0-1 inside with a 4PDT switch and the new A-11j mounted on the outside… a spaghetti mess in the box to get two transformer options.

so cool!
Have you had the opportunity to do any serious comparisons yet?

 

[j.colt]

No yet! That’s all the time I could squeeze tonight but I will check it out soon.
