I'm thinking strongly about building myself stereo pairs of the following crossovers (I'm assuming the 350Hz variant uses the same tube as the 50Hz low pass).




Rather than just buying the parts new over the net, I'd like to see if anyone already has the components (the small parts, the transformers, the sockets, the tubes, and possibly even a chassis) in their junk box and would be interested in trading them for a like value item from my offerings.

Anyone interested?

I'd like to put in a double order for parts (not the resistors or caps of course) for the second (350Hz) crossover. By daisy chaining two of these units together I'd have a basic clone of the Marchand XM126, so why not go the distance? Kind of nice that two 2nd order Butterworths make for a 4th order Linkwitz-Riley with the benefits of that alignment.

So, my preaching hasn´t fallen on deaf ears, has it?

You´re going active? Great.

Nope, I've been listening, just need to get the parts so I can get to it. So, anyone have a junk box full they're willing to trade?

Been playing around with "fool's triamping" this morning and am enjoying the results. For my Infinities running below 70Hz, I've ~200wpc (into 4 ohms) going to them, whatever my Galaxy Commander can put into 4 ohms (likely a good 200wpc on its own) on the <350Hz input of my Flatlines, and my little Fisher tube amp (15wpc) on the ribbons. Definitely sounds less strained now, so I can only imagine how it would sound with my poor man's Marchand XM126, should I ever obtain the parts.

Thanks to a cool link from Jorge, I'd like to slightly modify my request to what's needed to make this other crossover:
