I will say this again......
Mine works perfect!!!!
If you use anything other then what was used in the original...Asking for problems. IMHO.
The 300 ohm Verniers must be wire wound.....
Centralab WN or WW 300 are the PROPER ones. 
Langevin where used in 90% of the 176,s  600/600 ohm. ( Some Daven) I have seen in person and on 100,s of pictures of actual
176,s......
I copied mine down to the exact! Screws etc.......
My only gripe with this kit is the PCB,s are to THIN! And to long......They need to be shorter and thicker.
And better quality silver traces.
Check every solder joint!!!
My Attenuation works perfect on my unit.....Just like my 175b.......At 21:1 ratio sounds JUST like my 175b........

Like this, then?



C1, C2, C6, C7 tied back to transformer CT. Regulator reference is audio ground, which ties back to chassis and safety ground at one point (not shown).

To those with the Haufe transformers - how are you mounting them on the Rev B boards? Are modifications to the PCB required? I'm gently playing Tetris here trying to find a fit, but worried about the delicate leads on the trans. Any pics of your installs or guidance would be much appreciated. Thanks!

Nice!  Pre-aged parts, so when completed, your mixer can immediately considered 'vintage' (...)  ;-)

Those knobs, looks like the type as used on early Peavey guitar-amps ?

Lot's of problems with that circuit.

Signal output on common of pad is just grounded. That's not going to work.

You would need to switch both pins 2 and 3 of XLR in to the primary or pin 3 hot will not work. Also you don't need ground there to make a pad. Use a balanced pad. And you need 15K in series with each leg for reasons previously explained. So make an H pad with 15K output legs and two pole switch to switch to transformer.

The "Thru" connection isn't in if "Merge" is engaged? Just connect tip-to-tip and move RCA directly to 1K.

But other than that, I'm sure all of your dreams will be fulfilled once completed.

They are named "Billington exports" - website seem to be moved recently (was always near-analogue)

Easy EDA is what I downloaded, can't say if it's good or not yet.  I'm used to Protel but don't have a Windows machine now and not really interested in messing with Bootcamp on the Mac Pro. 
Believe it or not, I grabbed a thing called PCB Droid for Android and am messing about with it right now on a cheap Samsung tablet.  I was expecting it to be a joke but it really doesn't seem to be so for simple stuff like audio.  And I like not being tethered to a desk or a laptop.

OK yep, thought you may be in California, my old neck of the woods.

Regarding dimensions etc - You said 35mm per amp to line up with the channel widths which is good.  But what centre spacing are the transformers?  Coupling between them (crosstalk) is something I haven't checked as they're usually inside individual cases.  Anyway, might not be an issue but just a thought
