Hi everyone.
I saw an interview with Nelson Pass where he talks about the process of learning to develop the amplifier circuits. He has a good story about making a sort of "box" for changing around components to test new circuits while prototyping new amplifiers.
Has anyone ever seen a circuit for something like that?
It would be cool if Nelson was lurking and could expand on this a little bit.
Thanks for reading my post.

No, it is not a breadboard.
If you watch the video, it is set at the exact part of the conversation where Nelson explains it.
I understand the concept of what he is talking about. Indeed, it's a simple idea to understand.
I just have not ever built one like it and wondered if anyone had, besides Nelson.
he's talking about xover project box
you know what's "resistor decade box" ?
something as that, but not one resulting value - more like standard value set of resistors, which you can all wire by wish
then imagine 3 sets in one big box - set of Rs, set of Cs and set of Ls
then imagine all that having frontal set of connections as old Telephone Switching box, labeled of course
nice gizmo, but conditio sine qua non is brain of operator
gimme all shiny toys, ZM is usually too dumb to get past Power On click phase

Thank you.
Yes, that is what he said. Like an operator. I understand the concept.
Regarding the resistor decade box, thanks for that. I didn't know about it. I'm a complete newbie with electronics.
You could also get a set of nominal R’s, C’s, and L’s and a bag of Wago connectors. This lets me wire up any crossover I can come up with in about 15 minutes to listen to the speaker and voice it. The snap-lock Wago connectors let’s one swap out values quickly to fine tune the voicing, such as R padding etc.
Here is my set of nominal L, R, and C’s. It cost about $225 from Parts Express, but one of the best speaker building investments I have made. The instant gratification of hearing your XO right away vs waiting a week for parts to show up is really rewarding.
Here is an example of a 3-way I threw together after making the simulation in Xsim:
This an example of the effect of tweaking the padding resistor (4 different values) for the tweeter by swapping out the R’s using Wago connectors. Not as slick as a patch panel, but not bad and quite fast. Also, the Wago connectors are supposedly good for some insane 20A current.
