    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.

    JBL 3155 network.

    Has been awhile from this thread but if this message goes through! I would need help to find a clear schematic and a list of components.
    building a pair of 4355 and the network is my only component missing.

    thanks for any help!

    Unfortunately that network requires specific tapped autoformers which are no longer available. If one has the patience to search these forums there are equivalent networks posted... I don't have the time or patience to do the searching though.
