Re: OA-12 diskanerna funkar inte

I suspect one of the screws from the base has gone into one of the wires and created a short this is easy to do when reassembling sonab check your wiring from the crossover and ensure it is flowed through the correct chamber otherwise the screw will pinch the wiring and cause this problem.

Re: mint condition pair of OA-12s (and what happened to the forum format?)

No worries also can you take a photo of your crossovers? I just discovered there are two crossover designs for the sonab oa -12 and I own a pair with the earlier design maybe you have this version also? Check my thread about it - the early version seems more primitive than the common one we all know...

Re: mint condition pair of OA-12s (and what happened to the forum format?)

Given their age I'd recap the crossovers takes only an hour to do both and pretty inexpensive exercise. I'd also check the jumpers to ensure the contacts are clean and making good contact also while you are removing the crossover check that the woofer is in fact an original sc-165 many peerless woof...

Sonab oa-12 crossover

Hi all sonab experts I'm currently restoring a pair of sonab oa-12 and to my surprise I've noticed a different crossover fitted. I'm certain these are original and never tampered with no evidence of anyone soldering or removing them before me. There is no 10uf capacitor just a 5.6uf has anyone come ...

Re: Sb acoustic substitute for sonab?

Thanks for that I am also aware of this model you suggest but it's too expensive the ones listed that I mentioned seems much cheaper and I wonder if it is a close match to original sc165?
