PSW1000 question

realjeeprealjeep Posts: 1
So my PSW1000 amp died in a way that I don't think I can repair (some traces blown on the power input board). So I am looking for some options.

Does anyone know for sure the impedance of these drivers? It looks like the part # is RD8085-1 (x2 in series). I have been googling around and found several places that say 4 ohm each, but also a few places that say 2 ohm. I would like to drive them with an old Carver TFM-35, but the amp's manual is adamant about the speaker being at least 8 ohm in bridge mode and I definitely don't want to kill it.

    Since you are just dealing with a fairly simple voice coil measurement of the woofer you can probably get a good idea of the load by measuring the DC resistance with a volt/ohm meter. There's no crossover network to add reactance to the task and it's mostly the low value of the load you're most interested in anyway.
