Someone brought me an old Wharfedale model W-90 monitor speaker, a massive old beast with two highs, two midranges, and two 15" woofers. The problem was that the crossover circuits are damaged; two 50 ohm potentiometers were burned up, and someone had attempted to bypass them, getting the wiring mixed up in the process. I've drawn up a diagram of the components, numbering each component lead rather than show how they were hooked up. You can view the diagram here:
I'm hoping that someone can figure out the arrangement, and rather than have to draw up a schematic for me, you can just point out which numbers to connect. Some notes:
-the connections between the high and midrange speakers appear to be original, though I cannot be certain
-the woofers are presently connected in series (each measures 4 ohms)
-values of the other components are as follows: C1 - 25 uF 50VDC C2 - 12 uF 25VAC (much larger than C1) L1, L2 - values unknown, but both look identical VR1, VR2 - 50 ohms, 5 watts wirewound
I played around for a while and was able to achieve a decent sound with the following configuration: 1-3-8-13, 2-18-24, 22-23, 4-5, 7-17, 9-10, 11-19,14-21. This doesn't seem right though, since only two leads of each pot are used, and L2 isn't used at all.... Any help with this would be appreciated.
