I will test my woofers with the 9V battery...I already printed out your instructions. Should be easy. Thanks for the further explanation of my crossover, also. Based on what you told me, I interpreted I should be OK using the Platinum ALS wiring diagram and parts list "as is" as my replacement capacitors reference, since my crossover is identical, 'cept for some minor nuances as noted.
Yes, you did get confused on the silver cap specs: mine was 150uF and 100VNP (the actual cap says "150MFD 100WV"). You can see it on one of the last 5 pics (#15?). There is more writing on it, but its hard to read, and at this point, i think its moot and we have it figured out anyway.
My new 150uF 100VNP caps will be in this week, so I hope to solder one in soon, see what i got, and go from there. It's only a 150uF 100VNP (would go 150VNP now with the new knowledge), but I got spares (bought 5), and I'm nipping at the bit to get the speaker working again ASAP!
Then I'll communicate with Sonicraft and see what my other cap options are! And the woofer situation will also be on the back of my mind. I mean, these woofers are 15-20 years old now, and although they don't have a butt-load of hours on them (maybe 100-200 because they sat for years and years unused waiting for a bigger space and the right amps to power them), and while the woofers look pretty good, they may in fact be dried out or who knows what. Heck, the guy at Sonicraft told me electrolytic caps dry up and go bad too over many years, so who knows what sonic probems i may have. On the other hand, the speakers sound great: very clear, very smooth...its not fatiguing at all to listen to loudly. But from what I hear people say about ALS's bass, I think my bass is substandard.
But I like a lot of bass, and I've listened to rock music and jet engines all my life, not to mention loud cars, so it may be my hearing that's substandard!
Then we could talk speaker placement. But that's another topic. I already read some stuff in the Forum on it, and no doubt I am keeping my speakers away from side walls, with the ribbons towards the center---but speaker placement from the back wall and toe in dynamics sound arguable; I mean, the ALS owners manual says you can put them close to the back wall and have no loss of sound quality. I mean, this is Bob Carver talking.
I'll get back to you maybe tomorrow on the woofer test...I can't wait now!
