Why wouldn't you just build your own?

A number of months ago after discovering that the autoformers used in the 3155 crossover were no longer available from JBL Parts or anywhere else I asked for help on this forum.

Giskard came to the rescue and with the help of Greg Timbers (original designer of the 3155). Together they came up with an equivalent circuit replacing the autoformers with R-L networks.

I built them for my 4355 clones and they work wonderfully The parts cost around $250. I used premium parts and then dialed them in to a +/- 1% tolerance using my LCR meter.

If you are interested send me a PM and we can discuss it further. I would charge $450 to build another pair.
