May i ask which Haufe transformer you used?

Output is a 1:1 RK310/2 and on the input is one with the number '90468'. At Haufe they had no idea what it is. All I know is that it's from a Neumann console and is 2:1 step down. It doesn't work too well the other way around.

Neumann didn't even respond to my inquiry :o

Well, this is pretty awesome. Have you had the chance to compare it to a chandler tg1? I love mine but I wouldn't mind getting him a little brother.

Hi!

I went through BOM and have couple of questions.

Does it have to be BC559C? Can it be interchangeable with BC560C? They are almost the same except 559 is a bit lower max Vceo/Vcbo

And about 1N4153... is it interchangeable with 1N4148?

Just asking if I need to hunt those down or I can use more common types that I already have...

:)

You should be fine with the BC560C. I only took the 559 as I had hundreds of them at hand. :)

Can't really tell about the diodes. The compression knee might change a bit, but they should work...

Yes, I did. The new batch is here and ready to ship. I'm in the process of sending out notifications to everyone who reserved boards with me. Eventually everyone will get a response but it might take a day or two :)

SOLD OUT: PCBs for TG1 Zener Limiter
« Reply #33 on: April 03, 2017, 03:37:46 AM »
Ok, folks - that's it!!

Only one board is left - and that is mono. When this last pcb is gone, they're sold out.  :o

There are a few (potential) purchasers, who haven't replied to my notifications yet but I will wait until friday night (April, 7th). These reserved boards will become available again after friday if I don't get any response. Will keep you posted.

Please no more PMs about ordering 2 boards or more, there's only ONE left at the moment!

Picked up my boards at the P.O. today.  Very nice!  Time to start stuffing.  I built the Igor unit, and it will be interesting to compare the two builds.

Would love to hear your thoughts about the two.

I'll post more when I get it built.  I did have the opportunity to compare side-by-side my Igor build (with my optional "Neve" output section) with a Chandler, and I found that the tonal options were more with the "hold" control in place.  I could make the Igor version sound just like the Chandler version, but with the "hold" control, I had more options of "sound".
My $0.02, but YMMV.

Just for fun I tried it with the hold control but didn't like it that much. I was able to implement it by doing some off-board wiring; so it can be done with my boards, too. It's just not that straightforward to do so...  ;)

Studying your schematic now to see if it would be easy to add.  I really like the "hold" control option.  Would you care to publish your implementation?  If you show me yours, I'll show you mine.......:)
