Yeah, where did you get the little enclosure for the crossover?

Excellent. And, your observation is consistent with my urging, although that included you consider a Bryston 10B L-R. I never contemplated you'd build your own! But that's all you, Joe!
I'm curious about the error...
How'd you find it with everything still soldered to the PCB's? Compared one to the other...?
Smaart...?

"Indeed, not!!"
Thanks!

Their enclosures are really nice! Thick anodized front face, variety of sizes, and good prices.
Basically, the balanced output buffer is doubling the amplitude of the signal. At some point I had realized it would be a problem, but I forgot to correct for it until it was too late.
Luckily the short was on the bottom! It still took a while to find, at first I thought it was a faulty component and I clipped a bunch of them out.How'd you find it with everything still soldered to the PCB's? Compared one to the other...?
Yes! I have some ideas I want to run by you, when the time comes.Smaart...?
Lemme guess: 100nf + 3.92k? What a gem. When I grow up I want to be just as talented knowledgeable and resourcefull as just4kinks. Fabbing up proper quality products on your own is a great way of life. I'm holding my breath till you fire up the discrete balanced crossover. I'm sure it'll be a work of art. I'll hopefully be firing my 24db@340Hz single ended opamp crossover tomorrow - really similar desing to what you fabbed up. Hopefully it too will work some magic in the overall feel of my clones.
exactly! With 1% metal film resistors, and 1% mkp1837 (polypropylene metallized film) caps.
It's not talent and resource, it's just excessive free time! Besides, you have already proven your skills with your own beautiful clone project.What a gem.

post some pics! I want to see your handiwork.I'll hopefully be firing my 24db@340Hz single ended opamp crossover tomorrow - really similar desing to what you fabbed up. Hopefully it too will work some magic in the overall feel of my clones.
My clone project required me nearly only to solder the passive crossover and screw in the drivers - not too much work at all. Carpentry is an art, ordering cabs is not.
A couple of you have asked, and I finally have some progress to post: my discrete crossover is almost done!
I spent a lot of time earlier this year developing my discrete op-amp. It is completely BJT-based, with a class-A output stage. I probably won't make a plug-in version after all, there would be too many compromises and it's too hard to guarantee stability. So far I have designed a balanced I/O board and a Linkwitz-Riley filter board. Next will be a parametric filter board, and then an attenuator module.
This crossover uses the same basic circuit as the 5532 version I posted before. I added a couple tweaks, like muting relays and a provision for a gain control pot, although gain and frequency are still fixed, tuned for the 4345. I plugged it in to my system for this first time this weekend. It's a bit premature to describe how it sounds, I have to make some more tweaks and then I'll A/B test it against my 5532 version.

Damn! Looking very good. Great workmanship too. Well done!

I highly second the DAMN! Discrete analog crossover = pureness.
DAMN DAMN
A discrete active crossover... Wow, great and simply stunning work!
Wow. These are exceptional. Excellent attention to detail, and I love that you chose to finish them natural to bring out that beautiful ply.
You could just sell the pcb's for the start.
Some of us would be able to work with it.
Oh, and a sketch of schematic for it.
That would be
What do you estimate the cost of the enclosure to be?
