Hi all,
I have JBL PSW-D112 amplified subwoofer. Recently 2A fuse got blown. I couldn't find any bad parts on 2 small PCBs inside. The only thing which may be broken is S64AMI power amplifier module. That piece is filled with epoxy, so I cannot open it. Looks like I'll need to find replacement for this module.
I found this message on one of HAM user forums: The CK-72 germanium transistor made by Raytheon was a direct replacement for this module , it is however no longer made. Try using a Phillips
6CA7, it should just drop right in. But in all honesty, you would have better luck posting in an audiophile forum.I cannot find any references to either CK-72 or 6CA7 online.
Did anybody have experience fixing these subs or this particular amp module? Would Philips 6CA7 really replace S64AMI? Where can I find datasheets for above components?
Thank you very much!
